How do I find the factor combinations of the number 187,733,777?

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 187,733,777, 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.

1 187,733,777
-1 -187,733,777

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 187,733,777.

Example:
1 x 187,733,777 = 187,733,777
and
-1 x -187,733,777 = 187,733,777
Notice both answers equal 187,733,777

With that explanation out of the way, let's continue. Next, we take the number 187,733,777 and divide it by 2:

187,733,777 ÷ 2 = 93,866,888.5

If the quotient is a whole number, then 2 and 93,866,888.5 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:

1 187,733,777
-1 -187,733,777

Now, we try dividing 187,733,777 by 3:

187,733,777 ÷ 3 = 62,577,925.6667

If the quotient is a whole number, then 3 and 62,577,925.6667 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:

1 187,733,777
-1 -187,733,777

Let's try dividing by 4:

187,733,777 ÷ 4 = 46,933,444.25

If the quotient is a whole number, then 4 and 46,933,444.25 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:

1 187,733,777
-1 187,733,777
Keep dividing by the next highest number until you cannot divide anymore.

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

1711772,438,10117,066,70726,819,111187,733,777
