How do I find the factor combinations of the number 457,717?

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 457,717, 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.

1 457,717
-1 -457,717

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 457,717.

Example:
1 x 457,717 = 457,717
and
-1 x -457,717 = 457,717
Notice both answers equal 457,717

With that explanation out of the way, let's continue. Next, we take the number 457,717 and divide it by 2:

457,717 ÷ 2 = 228,858.5

If the quotient is a whole number, then 2 and 228,858.5 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:

1 457,717
-1 -457,717

Now, we try dividing 457,717 by 3:

457,717 ÷ 3 = 152,572.3333

If the quotient is a whole number, then 3 and 152,572.3333 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:

1 457,717
-1 -457,717

Let's try dividing by 4:

457,717 ÷ 4 = 114,429.25

If the quotient is a whole number, then 4 and 114,429.25 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:

1 457,717
-1 457,717
Keep dividing by the next highest number until you cannot divide anymore.

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

1131372571,7813,34135,209457,717
-1-13-137-257-1,781-3,341-35,209-457,717
