How do I find the factor combinations of the number 570,439?

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 570,439, 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.

1 570,439
-1 -570,439

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 570,439.

Example:
1 x 570,439 = 570,439
and
-1 x -570,439 = 570,439
Notice both answers equal 570,439

With that explanation out of the way, let's continue. Next, we take the number 570,439 and divide it by 2:

570,439 ÷ 2 = 285,219.5

If the quotient is a whole number, then 2 and 285,219.5 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:

1 570,439
-1 -570,439

Now, we try dividing 570,439 by 3:

570,439 ÷ 3 = 190,146.3333

If the quotient is a whole number, then 3 and 190,146.3333 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:

1 570,439
-1 -570,439

Let's try dividing by 4:

570,439 ÷ 4 = 142,609.75

If the quotient is a whole number, then 4 and 142,609.75 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:

1 570,439
-1 570,439
Keep dividing by the next highest number until you cannot divide anymore.

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

147532292,49110,76312,137570,439
-1-47-53-229-2,491-10,763-12,137-570,439
