How do I find the factor combinations of the number 655,895?

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 655,895, 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.

1 655,895
-1 -655,895

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 655,895.

Example:
1 x 655,895 = 655,895
and
-1 x -655,895 = 655,895
Notice both answers equal 655,895

With that explanation out of the way, let's continue. Next, we take the number 655,895 and divide it by 2:

655,895 ÷ 2 = 327,947.5

If the quotient is a whole number, then 2 and 327,947.5 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:

1 655,895
-1 -655,895

Now, we try dividing 655,895 by 3:

655,895 ÷ 3 = 218,631.6667

If the quotient is a whole number, then 3 and 218,631.6667 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:

1 655,895
-1 -655,895

Let's try dividing by 4:

655,895 ÷ 4 = 163,973.75

If the quotient is a whole number, then 4 and 163,973.75 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:

1 655,895
-1 655,895
Keep dividing by the next highest number until you cannot divide anymore.

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

152335631,1652,815131,179655,895
-1-5-233-563-1,165-2,815-131,179-655,895
