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 3,715,127, 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 | 3,715,127 | |
| -1 | -3,715,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,715,127.
Example:
1 x 3,715,127 = 3,715,127
and
-1 x -3,715,127 = 3,715,127
Notice both answers equal 3,715,127
With that explanation out of the way, let's continue. Next, we take the number 3,715,127 and divide it by 2:
3,715,127 ÷ 2 = 1,857,563.5
If the quotient is a whole number, then 2 and 1,857,563.5 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 | 3,715,127 | |
| -1 | -3,715,127 |
Now, we try dividing 3,715,127 by 3:
3,715,127 ÷ 3 = 1,238,375.6667
If the quotient is a whole number, then 3 and 1,238,375.6667 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 | 3,715,127 | |
| -1 | -3,715,127 |
Let's try dividing by 4:
3,715,127 ÷ 4 = 928,781.75
If the quotient is a whole number, then 4 and 928,781.75 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 | 3,715,127 | |
| -1 | 3,715,127 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 89 | 169 | 247 | 1,157 | 1,691 | 2,197 | 3,211 | 15,041 | 21,983 | 41,743 | 195,533 | 285,779 | 3,715,127 |
| -1 | -13 | -19 | -89 | -169 | -247 | -1,157 | -1,691 | -2,197 | -3,211 | -15,041 | -21,983 | -41,743 | -195,533 | -285,779 | -3,715,127 |
