How do I find the factor combinations of the number 665,261,425?

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 665,261,425, 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.

1 665,261,425
-1 -665,261,425

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 665,261,425.

Example:
1 x 665,261,425 = 665,261,425
and
-1 x -665,261,425 = 665,261,425
Notice both answers equal 665,261,425

With that explanation out of the way, let's continue. Next, we take the number 665,261,425 and divide it by 2:

665,261,425 ÷ 2 = 332,630,712.5

If the quotient is a whole number, then 2 and 332,630,712.5 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:

1 665,261,425
-1 -665,261,425

Now, we try dividing 665,261,425 by 3:

665,261,425 ÷ 3 = 221,753,808.3333

If the quotient is a whole number, then 3 and 221,753,808.3333 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:

1 665,261,425
-1 -665,261,425

Let's try dividing by 4:

665,261,425 ÷ 4 = 166,315,356.25

If the quotient is a whole number, then 4 and 166,315,356.25 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:

1 665,261,425
-1 665,261,425
Keep dividing by the next highest number until you cannot divide anymore.

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