How do I find the factors or divisors of the number 124,140,020?

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 124,140,020, 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.

1 124,140,020

Next, we take the number 124,140,020 and divide it by 2.

In this case, 124,140,020 ÷ 2 = 62,070,010

If the quotient is a whole number, then 2 and 62,070,010 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 62,070,010 124,140,020

Now, we try dividing 124,140,020 by 3.

124,140,020 ÷ 3 = 41,380,006.6667

If the quotient is a whole number, then 3 and 41,380,006.6667 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 62,070,010 124,140,020

Let's try dividing by 4.

124,140,020 ÷ 4 = 31,035,005

If the quotient is a whole number, then 4 and 31,035,005 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 4 31,035,005 62,070,010 124,140,020

We keep dividing by the next largest number, in this case the number 5. If the quotient of 124,140,020 ÷ 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:
