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 15,131,335, 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 | 15,131,335 | |
| -1 | -15,131,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,131,335.
Example:
1 x 15,131,335 = 15,131,335
and
-1 x -15,131,335 = 15,131,335
Notice both answers equal 15,131,335
With that explanation out of the way, let's continue. Next, we take the number 15,131,335 and divide it by 2:
15,131,335 ÷ 2 = 7,565,667.5
If the quotient is a whole number, then 2 and 7,565,667.5 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 | 15,131,335 | |
| -1 | -15,131,335 |
Now, we try dividing 15,131,335 by 3:
15,131,335 ÷ 3 = 5,043,778.3333
If the quotient is a whole number, then 3 and 5,043,778.3333 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 | 15,131,335 | |
| -1 | -15,131,335 |
Let's try dividing by 4:
15,131,335 ÷ 4 = 3,782,833.75
If the quotient is a whole number, then 4 and 3,782,833.75 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 | 15,131,335 | |
| -1 | 15,131,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 89 | 185 | 445 | 919 | 3,293 | 4,595 | 16,465 | 34,003 | 81,791 | 170,015 | 408,955 | 3,026,267 | 15,131,335 |
| -1 | -5 | -37 | -89 | -185 | -445 | -919 | -3,293 | -4,595 | -16,465 | -34,003 | -81,791 | -170,015 | -408,955 | -3,026,267 | -15,131,335 |
