How do I find the factors or divisors of the number 123,012,120?

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 123,012,120, 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.

1 123,012,120

Next, we take the number 123,012,120 and divide it by 2.

In this case, 123,012,120 ÷ 2 = 61,506,060

If the quotient is a whole number, then 2 and 61,506,060 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 61,506,060 123,012,120

Now, we try dividing 123,012,120 by 3.

123,012,120 ÷ 3 = 41,004,040

If the quotient is a whole number, then 3 and 41,004,040 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 41,004,040 61,506,060 123,012,120

Let's try dividing by 4.

123,012,120 ÷ 4 = 30,753,030

If the quotient is a whole number, then 4 and 30,753,030 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 30,753,030 41,004,040 61,506,060 123,012,120

We keep dividing by the next largest number, in this case the number 5. If the quotient of 123,012,120 ÷ 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:
