How do I find the factor combinations of the number 149,375?

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 149,375, 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.

1 149,375
-1 -149,375

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 149,375.

Example:
1 x 149,375 = 149,375
and
-1 x -149,375 = 149,375
Notice both answers equal 149,375

With that explanation out of the way, let's continue. Next, we take the number 149,375 and divide it by 2:

149,375 ÷ 2 = 74,687.5

If the quotient is a whole number, then 2 and 74,687.5 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:

1 149,375
-1 -149,375

Now, we try dividing 149,375 by 3:

149,375 ÷ 3 = 49,791.6667

If the quotient is a whole number, then 3 and 49,791.6667 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:

1 149,375
-1 -149,375

Let's try dividing by 4:

149,375 ÷ 4 = 37,343.75

If the quotient is a whole number, then 4 and 37,343.75 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:

1 149,375
-1 149,375
Keep dividing by the next highest number until you cannot divide anymore.

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

15251252396251,1955,97529,875149,375
-1-5-25-125-239-625-1,195-5,975-29,875-149,375
