How do I find the factor combinations of the number 578,462,323?

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 578,462,323, 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.

1 578,462,323
-1 -578,462,323

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 578,462,323.

Example:
1 x 578,462,323 = 578,462,323
and
-1 x -578,462,323 = 578,462,323
Notice both answers equal 578,462,323

With that explanation out of the way, let's continue. Next, we take the number 578,462,323 and divide it by 2:

578,462,323 ÷ 2 = 289,231,161.5

If the quotient is a whole number, then 2 and 289,231,161.5 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:

1 578,462,323
-1 -578,462,323

Now, we try dividing 578,462,323 by 3:

578,462,323 ÷ 3 = 192,820,774.3333

If the quotient is a whole number, then 3 and 192,820,774.3333 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:

1 578,462,323
-1 -578,462,323

Let's try dividing by 4:

578,462,323 ÷ 4 = 144,615,580.75

If the quotient is a whole number, then 4 and 144,615,580.75 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:

1 578,462,323
-1 578,462,323
Keep dividing by the next highest number until you cannot divide anymore.

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

1471,5318,03971,957377,83312,307,709578,462,323
