How do I find the factors or divisors of the number 123,456,788?

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 123,456,788, 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.

1 123,456,788

Next, we take the number 123,456,788 and divide it by 2.

In this case, 2 ÷ 123,456,788 = 61,728,394

If the quotient is a whole number, then 2 and 61,728,394 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 61,728,394 123,456,788

Now, we try dividing 123,456,788 by 3.

123,456,788 ÷ 3 = 41,152,262.6667

If the quotient is a whole number, then 3 and 41,152,262.6667 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 61,728,394 123,456,788

Let's try dividing by 4.

123,456,788 ÷ 4 = 30,864,197

If the quotient is a whole number, then 4 and 30,864,197 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 30,864,197 61,728,394 123,456,788

We keep dividing by the next largest number, in this case the number 5. If the quotient of 5 ÷ 123,456,788 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:
