How do I find the factor combinations of the number 65,213,892?

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 65,213,892, 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 65,213,892
-1 -65,213,892

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 65,213,892.

Example:
1 x 65,213,892 = 65,213,892
and
-1 x -65,213,892 = 65,213,892
Notice both answers equal 65,213,892

With that explanation out of the way, let's continue. Next, we take the number 65,213,892 and divide it by 2:

65,213,892 ÷ 2 = 32,606,946

If the quotient is a whole number, then 2 and 32,606,946 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 32,606,946 65,213,892
-1 -2 -32,606,946 -65,213,892

Now, we try dividing 65,213,892 by 3:

65,213,892 ÷ 3 = 21,737,964

If the quotient is a whole number, then 3 and 21,737,964 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 21,737,964 32,606,946 65,213,892
-1 -2 -3 -21,737,964 -32,606,946 -65,213,892

Let's try dividing by 4:

65,213,892 ÷ 4 = 16,303,473

If the quotient is a whole number, then 4 and 16,303,473 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 16,303,473 21,737,964 32,606,946 65,213,892
-1 -2 -3 -4 -16,303,473 -21,737,964 -32,606,946 65,213,892
Keep dividing by the next highest number until you cannot divide anymore.

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