How do I find the factor combinations of the number 162,175?

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 162,175, 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.

1 162,175
-1 -162,175

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 162,175.

Example:
1 x 162,175 = 162,175
and
-1 x -162,175 = 162,175
Notice both answers equal 162,175

With that explanation out of the way, let's continue. Next, we take the number 162,175 and divide it by 2:

162,175 ÷ 2 = 81,087.5

If the quotient is a whole number, then 2 and 81,087.5 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:

1 162,175
-1 -162,175

Now, we try dividing 162,175 by 3:

162,175 ÷ 3 = 54,058.3333

If the quotient is a whole number, then 3 and 54,058.3333 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:

1 162,175
-1 -162,175

Let's try dividing by 4:

162,175 ÷ 4 = 40,543.75

If the quotient is a whole number, then 4 and 40,543.75 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:

1 162,175
-1 162,175
Keep dividing by the next highest number until you cannot divide anymore.

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

151325653254992,4956,48712,47532,435162,175
