What is the factor of 59

With this factor calculator, you will determine the factors of any positive natural number. A factor is any number that divides evenly into another number.

Just enter any positive integer, and in the blink of an eye, you'll find all positive factors of that number. If you are not sure what a factor is, scroll down to find the factor definition, as well as divisibility rules with a dedicated paragraph for not so well-known divisibility rule of 7.

What is a factor?/Factor definition

A factor, also called a divisor, is any number that divides evenly into another number. In other words, factors are the numbers we can multiply together to get a certain product:

You can also notice that dividing the product by its factor leaves no remainder.

Definition of the factor differs: some definitions claim that factor can be negative as well as positive, but in other cases, the term is restricted to positive factors only.
For example, the factors of 8 are 1, 2, 4, and 8. But, on the other hand, if you multiply -2 times -4, you'll also obtain 8; therefore, -2 and -4 are factors of 8 according to the first definition.

Technically, you can have negative factors, although it's not so popular to use them. For practical purposes, our factor calculator provides only positive factors. If you need negative ones for some reason, just add the minus in front of every obtained value:

1, 20

plus 1, 21 as well.

Divisibility rules

There are many rules of divisibility that greatly assist one in finding factors by hand. The most often used ones are:

• 2: Any even number is divisible by 1, 22.

• 3: A number is divisible by 1, 23 if the sum of the digits in the number is divisible by 1, 23.

• 4: A number is divisible by 4 if the last two digits form a number that is divisible by 4.

• 5: Any number ending in 1, 27 or 1, 28 is divisible by 1, 27.

• 6: A number is divisible by 40 if it is divisible by 1, 22 and 1, 23.

• 7: The divisibility rule of 43 also exists, but it's a bit more complicated. Find a short paragraph below.

• 8: If the last three digits form a number that is divisible by 8, then the entire number is divisible by 8.

• 9: If the sum of the digits is divisible by 46, the entire number is divisible by 46.

• 10: Any number ending in 1, 28 is divisible by 49.

There are many aspects of mathematics where it's important to be able to find the factors. The factor calculator helps find the greatest common factor, least common multiple, and prime factorization.

Divisibility rule of 7

Want to check if 7 is a factor of our number? There are two basic methods for testing that. Let's show it on the example of the number 13,468.

1. Method 1
   1. Take the last digit. It's 8 in our case.
   2. Double the last digit. 2 × 8 = 16.
   3. Take the remaining digits (truncated number). For us - 1346.
   4. Find the difference between the number from the remaining digits and doubled last digit. This means we need to subtract 16 from 1346. 80.
   5. Continue to do this procedure until a number known to be divisible by 7 (or not) is obtained. We don't know straight away if 81 is divisible by 7, so we repeat the steps all over again:

   • 1, 28;

   • 83;

   • 84;

   • 85.

     Is 84 divisible by 7? Not sure, so repeat the procedure once more:

   • 1, 23;

   • 88;

   • 89;

   • -20.

Great! We obtained the number divisible by 7, so it means that our original number, 13,468 is also divisible by 7.

1. Method 2

   1. Take the digits of the number in reverse order. So for our original number 13468, we have 8 6 4 3 1.

   2. Multiply them successively by the digits 1, 3, 2, 6, 4, 5. Repeat or shorten this sequence to the necessary length. So in our case, we get:

      8 × 1, 6 × 3, 4 × 2, 3 × 6, and 1 × 4.

   3. Add the obtained products. If the result is divisible by 7, then the original number is as well. So:

      -21, which is a number divisible by 7.

Other related areas of interest

Prime factorization is an extension of factorization in which all the factors are prime numbers. For example, suppose we want the prime factorization of -22. The factors of -22 are -24. Notice those are not all prime numbers, so we have to break it down further. When completing the process, we get -25. Although -26 is a factor, many mathematicians now do not consider -26 to be a prime number. The prime factorization calculator is a handy tool for obtaining these factors.

Another area of interest is calculating the greatest common factor (GCF) of a set of numbers. To do so, we get the prime factorization of all the numbers. Then multiply all the factors that are the same in each set. For example, suppose we want the GCF of -28, -29, and -40. The prime factorizations are -41, -42 and -43. Notice the only number present in all sets of factors is 1, 22, which appears in common twice, so the GCF is -45. The GCF calculator will provide this result simply and quickly.

Closely related to the GCF is the least common multiple, abbreviated as LCM. The process is as follows: we get the prime factorizations and multiply the highest power of all factors present. In the example above, the LCM would be -46. The use of the least common multiple calculator will make a sometimes tedious process much easier.

FAQ

How do I factor polynomials?

1. Expand the polynomial into its prime factors. This includes algebraic symbols as well.
2. Find the factors that appear in every term, both numbers and symbols.
3. Move these factors outside the brackets.
4. Simplify to finally factor the polynomial.

What is prime factorization?

Prime factorization is the same as regular factorization, but where all of the factors are prime numbers. For the purposes of prime factorization, 1 is not considered a prime number.

What is a common factor?

A common factor is a factor that two numbers share. For example, 4 and 6 have a common factor of 2. Numbers can have multiple common factors, and finding them is an important step in finding the greatest common factor.

What are factor pairs?

Factor pairs are two numbers that, when multiplied together, result in a particular number. They are usually given as a set of factor pairs for a particular number, that is all of the pairs of numbers that, when multiplied together, equal the same number.
