How do I find the factors or divisors of the number 72,870,072?

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 72,870,072, 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 72,870,072

Next, we take the number 72,870,072 and divide it by 2.

In this case, 72,870,072 ÷ 2 = 36,435,036

If the quotient is a whole number, then 2 and 36,435,036 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 36,435,036 72,870,072

Now, we try dividing 72,870,072 by 3.

72,870,072 ÷ 3 = 24,290,024

If the quotient is a whole number, then 3 and 24,290,024 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:

1 2 3 24,290,024 36,435,036 72,870,072

Let's try dividing by 4.

72,870,072 ÷ 4 = 18,217,518

If the quotient is a whole number, then 4 and 18,217,518 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:

1 2 3 4 18,217,518 24,290,024 36,435,036 72,870,072

We keep dividing by the next largest number, in this case the number 5. If the quotient of 72,870,072 ÷ 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:
