Q: What are the factors or divisors of the number 391,120?

How do I find the factors or divisors of the number 391,120?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the factors of larger numbers. To find the factors of the number 391,120, it is easiest to start from the outside in. Here's what we mean:

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table.

1

391,120

Next, we take the number 391,120 and divide it by 2.

In this case, 391,120 ÷ 2 = 195,560

If the quotient is a whole number, then 2 and 195,560 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Now, we try dividing 391,120 by 3.

391,120 ÷ 3 = 130,373.3333

If the quotient is a whole number, then 3 and 130,373.3333 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

Let's try dividing by 4.

391,120 ÷ 4 = 97,780

If the quotient is a whole number, then 4 and 97,780 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

We keep dividing by the next largest number, in this case the number 5. If the quotient of 391,120 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.

Keep dividing by the next highest number until you cannot divide anymore.

What you will end up with is this table:

All of the numbers in the table above can be evenly divided into the number 391,120.

Finally, for your reference, here are all of the divisor combinations of the number 391,120:
