How do I find the factor combinations of the number 61,510,584?

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 61,510,584, 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 61,510,584
-1 -61,510,584

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 61,510,584.

Example:
1 x 61,510,584 = 61,510,584
and
-1 x -61,510,584 = 61,510,584
Notice both answers equal 61,510,584

With that explanation out of the way, let's continue. Next, we take the number 61,510,584 and divide it by 2:

61,510,584 ÷ 2 = 30,755,292

If the quotient is a whole number, then 2 and 30,755,292 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 30,755,292 61,510,584
-1 -2 -30,755,292 -61,510,584

Now, we try dividing 61,510,584 by 3:

61,510,584 ÷ 3 = 20,503,528

If the quotient is a whole number, then 3 and 20,503,528 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 20,503,528 30,755,292 61,510,584
-1 -2 -3 -20,503,528 -30,755,292 -61,510,584

Let's try dividing by 4:

61,510,584 ÷ 4 = 15,377,646

If the quotient is a whole number, then 4 and 15,377,646 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 15,377,646 20,503,528 30,755,292 61,510,584
-1 -2 -3 -4 -15,377,646 -20,503,528 -30,755,292 61,510,584
Keep dividing by the next highest number until you cannot divide anymore.

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