How do I find the factor combinations of the number 63,064,355?

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 63,064,355, 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 63,064,355
-1 -63,064,355

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 63,064,355.

Example:
1 x 63,064,355 = 63,064,355
and
-1 x -63,064,355 = 63,064,355
Notice both answers equal 63,064,355

With that explanation out of the way, let's continue. Next, we take the number 63,064,355 and divide it by 2:

63,064,355 ÷ 2 = 31,532,177.5

If the quotient is a whole number, then 2 and 31,532,177.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 63,064,355
-1 -63,064,355

Now, we try dividing 63,064,355 by 3:

63,064,355 ÷ 3 = 21,021,451.6667

If the quotient is a whole number, then 3 and 21,021,451.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 63,064,355
-1 -63,064,355

Let's try dividing by 4:

63,064,355 ÷ 4 = 15,766,088.75

If the quotient is a whole number, then 4 and 15,766,088.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 63,064,355
-1 63,064,355
Keep dividing by the next highest number until you cannot divide anymore.

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

1541205307,6311,538,15512,612,87163,064,355
-1-5-41-205-307,631-1,538,155-12,612,871-63,064,355
