How do I find the factor combinations of the number 140,885?

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 140,885, 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.

1 140,885
-1 -140,885

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 140,885.

Example:
1 x 140,885 = 140,885
and
-1 x -140,885 = 140,885
Notice both answers equal 140,885

With that explanation out of the way, let's continue. Next, we take the number 140,885 and divide it by 2:

140,885 ÷ 2 = 70,442.5

If the quotient is a whole number, then 2 and 70,442.5 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:

1 140,885
-1 -140,885

Now, we try dividing 140,885 by 3:

140,885 ÷ 3 = 46,961.6667

If the quotient is a whole number, then 3 and 46,961.6667 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:

1 140,885
-1 -140,885

Let's try dividing by 4:

140,885 ÷ 4 = 35,221.25

If the quotient is a whole number, then 4 and 35,221.25 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:

1 140,885
-1 140,885
Keep dividing by the next highest number until you cannot divide anymore.

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

1519951,4837,41528,177140,885
-1-5-19-95-1,483-7,415-28,177-140,885
