How do I find the factor combinations of the number 357,847?

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 357,847, 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.

1 357,847
-1 -357,847

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 357,847.

Example:
1 x 357,847 = 357,847
and
-1 x -357,847 = 357,847
Notice both answers equal 357,847

With that explanation out of the way, let's continue. Next, we take the number 357,847 and divide it by 2:

357,847 ÷ 2 = 178,923.5

If the quotient is a whole number, then 2 and 178,923.5 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:

1 357,847
-1 -357,847

Now, we try dividing 357,847 by 3:

357,847 ÷ 3 = 119,282.3333

If the quotient is a whole number, then 3 and 119,282.3333 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:

1 357,847
-1 -357,847

Let's try dividing by 4:

357,847 ÷ 4 = 89,461.75

If the quotient is a whole number, then 4 and 89,461.75 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:

1 357,847
-1 357,847
Keep dividing by the next highest number until you cannot divide anymore.

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

1749671094697633,2835,3417,30351,121357,847
-1-7-49-67-109-469-763-3,283-5,341-7,303-51,121-357,847
