How do I find the factors or divisors of the number 121,205,620?

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 121,205,620, 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.

1 121,205,620

Next, we take the number 121,205,620 and divide it by 2.

In this case, 121,205,620 ÷ 2 = 60,602,810

If the quotient is a whole number, then 2 and 60,602,810 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 60,602,810 121,205,620

Now, we try dividing 121,205,620 by 3.

121,205,620 ÷ 3 = 40,401,873.3333

If the quotient is a whole number, then 3 and 40,401,873.3333 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:

1 2 60,602,810 121,205,620

Let's try dividing by 4.

121,205,620 ÷ 4 = 30,301,405

If the quotient is a whole number, then 4 and 30,301,405 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 30,301,405 60,602,810 121,205,620

We keep dividing by the next largest number, in this case the number 5. If the quotient of 121,205,620 ÷ 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:
