How do I find the factor combinations of the number 86,735?

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 86,735, 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 86,735
-1 -86,735

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 86,735.

Example:
1 x 86,735 = 86,735
and
-1 x -86,735 = 86,735
Notice both answers equal 86,735

With that explanation out of the way, let's continue. Next, we take the number 86,735 and divide it by 2:

86,735 ÷ 2 = 43,367.5

If the quotient is a whole number, then 2 and 43,367.5 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 86,735
-1 -86,735

Now, we try dividing 86,735 by 3:

86,735 ÷ 3 = 28,911.6667

If the quotient is a whole number, then 3 and 28,911.6667 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 86,735
-1 -86,735

Let's try dividing by 4:

86,735 ÷ 4 = 21,683.75

If the quotient is a whole number, then 4 and 21,683.75 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 86,735
-1 86,735
Keep dividing by the next highest number until you cannot divide anymore.

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

1511195583952094159131,0451,5774,5657,88517,34786,735
-1-5-11-19-55-83-95-209-415-913-1,045-1,577-4,565-7,885-17,347-86,735
