How do I find the factor combinations of the number 65,131,332?

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 divisors of larger numbers. To find the factor combinations of the number 65,131,332, it is easier to work with a table - it's called factoring from the outside in.

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. Then, below that, write the numbers as a negative as well.

1 65,131,332
-1 -65,131,332

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,131,332.

Example:
1 x 65,131,332 = 65,131,332
and
-1 x -65,131,332 = 65,131,332
Notice both answers equal 65,131,332

With that explanation out of the way, let's continue. Next, we take the number 65,131,332 and divide it by 2:

65,131,332 ÷ 2 = 32,565,666

If the quotient is a whole number, then 2 and 32,565,666 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 32,565,666 65,131,332
-1 -2 -32,565,666 -65,131,332

Now, we try dividing 65,131,332 by 3:

65,131,332 ÷ 3 = 21,710,444

If the quotient is a whole number, then 3 and 21,710,444 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 21,710,444 32,565,666 65,131,332
-1 -2 -3 -21,710,444 -32,565,666 -65,131,332

Let's try dividing by 4:

65,131,332 ÷ 4 = 16,282,833

If the quotient is a whole number, then 4 and 16,282,833 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 16,282,833 21,710,444 32,565,666 65,131,332
-1 -2 -3 -4 -16,282,833 -21,710,444 -32,565,666 65,131,332
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:
