How do I find the factor combinations of the number 785,567?

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 785,567, 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.

1 785,567
-1 -785,567

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 785,567.

Example:
1 x 785,567 = 785,567
and
-1 x -785,567 = 785,567
Notice both answers equal 785,567

With that explanation out of the way, let's continue. Next, we take the number 785,567 and divide it by 2:

785,567 ÷ 2 = 392,783.5

If the quotient is a whole number, then 2 and 392,783.5 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:

1 785,567
-1 -785,567

Now, we try dividing 785,567 by 3:

785,567 ÷ 3 = 261,855.6667

If the quotient is a whole number, then 3 and 261,855.6667 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:

1 785,567
-1 -785,567

Let's try dividing by 4:

785,567 ÷ 4 = 196,391.75

If the quotient is a whole number, then 4 and 196,391.75 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:

1 785,567
-1 785,567
Keep dividing by the next highest number until you cannot divide anymore.

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

14318,269785,567
-1-43-18,269-785,567
