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 12,633,325, 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 | 12,633,325 | |
| -1 | -12,633,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,633,325.
Example:
1 x 12,633,325 = 12,633,325
and
-1 x -12,633,325 = 12,633,325
Notice both answers equal 12,633,325
With that explanation out of the way, let's continue. Next, we take the number 12,633,325 and divide it by 2:
12,633,325 ÷ 2 = 6,316,662.5
If the quotient is a whole number, then 2 and 6,316,662.5 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 | 12,633,325 | |
| -1 | -12,633,325 |
Now, we try dividing 12,633,325 by 3:
12,633,325 ÷ 3 = 4,211,108.3333
If the quotient is a whole number, then 3 and 4,211,108.3333 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 | 12,633,325 | |
| -1 | -12,633,325 |
Let's try dividing by 4:
12,633,325 ÷ 4 = 3,158,331.25
If the quotient is a whole number, then 4 and 3,158,331.25 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 | 12,633,325 | |
| -1 | 12,633,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 127 | 173 | 575 | 635 | 865 | 2,921 | 3,175 | 3,979 | 4,325 | 14,605 | 19,895 | 21,971 | 73,025 | 99,475 | 109,855 | 505,333 | 549,275 | 2,526,665 | 12,633,325 |
| -1 | -5 | -23 | -25 | -115 | -127 | -173 | -575 | -635 | -865 | -2,921 | -3,175 | -3,979 | -4,325 | -14,605 | -19,895 | -21,971 | -73,025 | -99,475 | -109,855 | -505,333 | -549,275 | -2,526,665 | -12,633,325 |
