How do I find the factor combinations of the number 111,552,155?

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 111,552,155, 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.

1 111,552,155
-1 -111,552,155

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 111,552,155.

Example:
1 x 111,552,155 = 111,552,155
and
-1 x -111,552,155 = 111,552,155
Notice both answers equal 111,552,155

With that explanation out of the way, let's continue. Next, we take the number 111,552,155 and divide it by 2:

111,552,155 ÷ 2 = 55,776,077.5

If the quotient is a whole number, then 2 and 55,776,077.5 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:

1 111,552,155
-1 -111,552,155

Now, we try dividing 111,552,155 by 3:

111,552,155 ÷ 3 = 37,184,051.6667

If the quotient is a whole number, then 3 and 37,184,051.6667 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:

1 111,552,155
-1 -111,552,155

Let's try dividing by 4:

111,552,155 ÷ 4 = 27,888,038.75

If the quotient is a whole number, then 4 and 27,888,038.75 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:

1 111,552,155
-1 111,552,155
Keep dividing by the next highest number until you cannot divide anymore.

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