How do I find the factor combinations of the number 89,392,501?

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 89,392,501, 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 89,392,501
-1 -89,392,501

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 89,392,501.

Example:
1 x 89,392,501 = 89,392,501
and
-1 x -89,392,501 = 89,392,501
Notice both answers equal 89,392,501

With that explanation out of the way, let's continue. Next, we take the number 89,392,501 and divide it by 2:

89,392,501 ÷ 2 = 44,696,250.5

If the quotient is a whole number, then 2 and 44,696,250.5 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 89,392,501
-1 -89,392,501

Now, we try dividing 89,392,501 by 3:

89,392,501 ÷ 3 = 29,797,500.3333

If the quotient is a whole number, then 3 and 29,797,500.3333 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 89,392,501
-1 -89,392,501

Let's try dividing by 4:

89,392,501 ÷ 4 = 22,348,125.25

If the quotient is a whole number, then 4 and 22,348,125.25 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 89,392,501
-1 89,392,501
Keep dividing by the next highest number until you cannot divide anymore.

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

111121738,7818,126,59189,392,501
-1-11-121-738,781-8,126,591-89,392,501
