How do I find the factor combinations of the number 104,995?

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 104,995, 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.

1 104,995
-1 -104,995

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 104,995.

Example:
1 x 104,995 = 104,995
and
-1 x -104,995 = 104,995
Notice both answers equal 104,995

With that explanation out of the way, let's continue. Next, we take the number 104,995 and divide it by 2:

104,995 ÷ 2 = 52,497.5

If the quotient is a whole number, then 2 and 52,497.5 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:

1 104,995
-1 -104,995

Now, we try dividing 104,995 by 3:

104,995 ÷ 3 = 34,998.3333

If the quotient is a whole number, then 3 and 34,998.3333 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:

1 104,995
-1 -104,995

Let's try dividing by 4:

104,995 ÷ 4 = 26,248.75

If the quotient is a whole number, then 4 and 26,248.75 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:

1 104,995
-1 104,995
Keep dividing by the next highest number until you cannot divide anymore.

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

15112355831152534159131,2651,9094,5659,54520,999104,995
