How do I find the factor combinations of the number 785,747?

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 785,747, 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.

1 785,747
-1 -785,747

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 785,747.

Example:
1 x 785,747 = 785,747
and
-1 x -785,747 = 785,747
Notice both answers equal 785,747

With that explanation out of the way, let's continue. Next, we take the number 785,747 and divide it by 2:

785,747 ÷ 2 = 392,873.5

If the quotient is a whole number, then 2 and 392,873.5 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:

1 785,747
-1 -785,747

Now, we try dividing 785,747 by 3:

785,747 ÷ 3 = 261,915.6667

If the quotient is a whole number, then 3 and 261,915.6667 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:

1 785,747
-1 -785,747

Let's try dividing by 4:

785,747 ÷ 4 = 196,436.75

If the quotient is a whole number, then 4 and 196,436.75 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:

1 785,747
-1 785,747
Keep dividing by the next highest number until you cannot divide anymore.

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

13672,141785,747
-1-367-2,141-785,747
