How do I find the factor combinations of the number 53,315,016?

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 53,315,016, 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 53,315,016
-1 -53,315,016

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 53,315,016.

Example:
1 x 53,315,016 = 53,315,016
and
-1 x -53,315,016 = 53,315,016
Notice both answers equal 53,315,016

With that explanation out of the way, let's continue. Next, we take the number 53,315,016 and divide it by 2:

53,315,016 ÷ 2 = 26,657,508

If the quotient is a whole number, then 2 and 26,657,508 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 26,657,508 53,315,016
-1 -2 -26,657,508 -53,315,016

Now, we try dividing 53,315,016 by 3:

53,315,016 ÷ 3 = 17,771,672

If the quotient is a whole number, then 3 and 17,771,672 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 17,771,672 26,657,508 53,315,016
-1 -2 -3 -17,771,672 -26,657,508 -53,315,016

Let's try dividing by 4:

53,315,016 ÷ 4 = 13,328,754

If the quotient is a whole number, then 4 and 13,328,754 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 13,328,754 17,771,672 26,657,508 53,315,016
-1 -2 -3 -4 -13,328,754 -17,771,672 -26,657,508 53,315,016
Keep dividing by the next highest number until you cannot divide anymore.

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