How do I find the factor combinations of the number 85,718,875?

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 85,718,875, 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 85,718,875
-1 -85,718,875

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 85,718,875.

Example:
1 x 85,718,875 = 85,718,875
and
-1 x -85,718,875 = 85,718,875
Notice both answers equal 85,718,875

With that explanation out of the way, let's continue. Next, we take the number 85,718,875 and divide it by 2:

85,718,875 ÷ 2 = 42,859,437.5

If the quotient is a whole number, then 2 and 42,859,437.5 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 85,718,875
-1 -85,718,875

Now, we try dividing 85,718,875 by 3:

85,718,875 ÷ 3 = 28,572,958.3333

If the quotient is a whole number, then 3 and 28,572,958.3333 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 85,718,875
-1 -85,718,875

Let's try dividing by 4:

85,718,875 ÷ 4 = 21,429,718.75

If the quotient is a whole number, then 4 and 21,429,718.75 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 85,718,875
-1 85,718,875
Keep dividing by the next highest number until you cannot divide anymore.

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