How do I find the factor combinations of the number 223,951?

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 223,951, 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.

1 223,951
-1 -223,951

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 223,951.

Example:
1 x 223,951 = 223,951
and
-1 x -223,951 = 223,951
Notice both answers equal 223,951

With that explanation out of the way, let's continue. Next, we take the number 223,951 and divide it by 2:

223,951 ÷ 2 = 111,975.5

If the quotient is a whole number, then 2 and 111,975.5 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:

1 223,951
-1 -223,951

Now, we try dividing 223,951 by 3:

223,951 ÷ 3 = 74,650.3333

If the quotient is a whole number, then 3 and 74,650.3333 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:

1 223,951
-1 -223,951

Let's try dividing by 4:

223,951 ÷ 4 = 55,987.75

If the quotient is a whole number, then 4 and 55,987.75 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:

1 223,951
-1 223,951
Keep dividing by the next highest number until you cannot divide anymore.

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

171323911071612997491,3912,0932,4619,73717,22731,993223,951
