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 12,630,875, 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 | 12,630,875 | |
| -1 | -12,630,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,630,875.
Example:
1 x 12,630,875 = 12,630,875
and
-1 x -12,630,875 = 12,630,875
Notice both answers equal 12,630,875
With that explanation out of the way, let's continue. Next, we take the number 12,630,875 and divide it by 2:
12,630,875 ÷ 2 = 6,315,437.5
If the quotient is a whole number, then 2 and 6,315,437.5 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 | 12,630,875 | |
| -1 | -12,630,875 |
Now, we try dividing 12,630,875 by 3:
12,630,875 ÷ 3 = 4,210,291.6667
If the quotient is a whole number, then 3 and 4,210,291.6667 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 | 12,630,875 | |
| -1 | -12,630,875 |
Let's try dividing by 4:
12,630,875 ÷ 4 = 3,157,718.75
If the quotient is a whole number, then 4 and 3,157,718.75 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 | 12,630,875 | |
| -1 | 12,630,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 125 | 185 | 925 | 2,731 | 4,625 | 13,655 | 68,275 | 101,047 | 341,375 | 505,235 | 2,526,175 | 12,630,875 |
| -1 | -5 | -25 | -37 | -125 | -185 | -925 | -2,731 | -4,625 | -13,655 | -68,275 | -101,047 | -341,375 | -505,235 | -2,526,175 | -12,630,875 |
