How do I find the factor combinations of the number 350,945?

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 350,945, 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.

1 350,945
-1 -350,945

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 350,945.

Example:
1 x 350,945 = 350,945
and
-1 x -350,945 = 350,945
Notice both answers equal 350,945

With that explanation out of the way, let's continue. Next, we take the number 350,945 and divide it by 2:

350,945 ÷ 2 = 175,472.5

If the quotient is a whole number, then 2 and 175,472.5 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:

1 350,945
-1 -350,945

Now, we try dividing 350,945 by 3:

350,945 ÷ 3 = 116,981.6667

If the quotient is a whole number, then 3 and 116,981.6667 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:

1 350,945
-1 -350,945

Let's try dividing by 4:

350,945 ÷ 4 = 87,736.25

If the quotient is a whole number, then 4 and 87,736.25 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:

1 350,945
-1 350,945
Keep dividing by the next highest number until you cannot divide anymore.

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

15735371852592711,2951,3551,8979,48510,02750,13570,189350,945
