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 15,080,087, 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 | 15,080,087 | |
| -1 | -15,080,087 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,080,087.
Example:
1 x 15,080,087 = 15,080,087
and
-1 x -15,080,087 = 15,080,087
Notice both answers equal 15,080,087
With that explanation out of the way, let's continue. Next, we take the number 15,080,087 and divide it by 2:
15,080,087 ÷ 2 = 7,540,043.5
If the quotient is a whole number, then 2 and 7,540,043.5 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 | 15,080,087 | |
| -1 | -15,080,087 |
Now, we try dividing 15,080,087 by 3:
15,080,087 ÷ 3 = 5,026,695.6667
If the quotient is a whole number, then 3 and 5,026,695.6667 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 | 15,080,087 | |
| -1 | -15,080,087 |
Let's try dividing by 4:
15,080,087 ÷ 4 = 3,770,021.75
If the quotient is a whole number, then 4 and 3,770,021.75 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 | 15,080,087 | |
| -1 | 15,080,087 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 41 | 319 | 451 | 1,153 | 1,189 | 12,683 | 13,079 | 33,437 | 47,273 | 367,807 | 520,003 | 1,370,917 | 15,080,087 |
| -1 | -11 | -29 | -41 | -319 | -451 | -1,153 | -1,189 | -12,683 | -13,079 | -33,437 | -47,273 | -367,807 | -520,003 | -1,370,917 | -15,080,087 |
