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 12,117,175, it is easier to work with a table - it's called factoring from the outside in.
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 | 12,117,175 | |
| -1 | -12,117,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,117,175.
Example:
1 x 12,117,175 = 12,117,175
and
-1 x -12,117,175 = 12,117,175
Notice both answers equal 12,117,175
With that explanation out of the way, let's continue. Next, we take the number 12,117,175 and divide it by 2:
12,117,175 ÷ 2 = 6,058,587.5
If the quotient is a whole number, then 2 and 6,058,587.5 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 | 12,117,175 | |
| -1 | -12,117,175 |
Now, we try dividing 12,117,175 by 3:
12,117,175 ÷ 3 = 4,039,058.3333
If the quotient is a whole number, then 3 and 4,039,058.3333 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 | 12,117,175 | |
| -1 | -12,117,175 |
Let's try dividing by 4:
12,117,175 ÷ 4 = 3,029,293.75
If the quotient is a whole number, then 4 and 3,029,293.75 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 | 12,117,175 | |
| -1 | 12,117,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 25 | 35 | 85 | 119 | 175 | 425 | 595 | 2,975 | 4,073 | 20,365 | 28,511 | 69,241 | 101,825 | 142,555 | 346,205 | 484,687 | 712,775 | 1,731,025 | 2,423,435 | 12,117,175 |
| -1 | -5 | -7 | -17 | -25 | -35 | -85 | -119 | -175 | -425 | -595 | -2,975 | -4,073 | -20,365 | -28,511 | -69,241 | -101,825 | -142,555 | -346,205 | -484,687 | -712,775 | -1,731,025 | -2,423,435 | -12,117,175 |
