How do I find the factors or divisors of the number 42,243,324?

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 42,243,324, 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 42,243,324

Next, we take the number 42,243,324 and divide it by 2.

In this case, 42,243,324 ÷ 2 = 21,121,662

If the quotient is a whole number, then 2 and 21,121,662 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 21,121,662 42,243,324

Now, we try dividing 42,243,324 by 3.

42,243,324 ÷ 3 = 14,081,108

If the quotient is a whole number, then 3 and 14,081,108 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 14,081,108 21,121,662 42,243,324

Let's try dividing by 4.

42,243,324 ÷ 4 = 10,560,831

If the quotient is a whole number, then 4 and 10,560,831 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 10,560,831 14,081,108 21,121,662 42,243,324

We keep dividing by the next largest number, in this case the number 5. If the quotient of 42,243,324 ÷ 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:

12346125771,1541,7312,3083,4626,1016,92412,20218,30324,40436,60673,2123,520,2777,040,55410,560,83114,081,10821,121,66242,243,324

All of the numbers in the table above can be evenly divided into the number 42,243,324.
