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 15,425,707, 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 | 15,425,707 | |
| -1 | -15,425,707 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,425,707.
Example:
1 x 15,425,707 = 15,425,707
and
-1 x -15,425,707 = 15,425,707
Notice both answers equal 15,425,707
With that explanation out of the way, let's continue. Next, we take the number 15,425,707 and divide it by 2:
15,425,707 ÷ 2 = 7,712,853.5
If the quotient is a whole number, then 2 and 7,712,853.5 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 | 15,425,707 | |
| -1 | -15,425,707 |
Now, we try dividing 15,425,707 by 3:
15,425,707 ÷ 3 = 5,141,902.3333
If the quotient is a whole number, then 3 and 5,141,902.3333 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 | 15,425,707 | |
| -1 | -15,425,707 |
Let's try dividing by 4:
15,425,707 ÷ 4 = 3,856,426.75
If the quotient is a whole number, then 4 and 3,856,426.75 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 | 15,425,707 | |
| -1 | 15,425,707 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 151 | 251 | 407 | 1,661 | 2,761 | 5,587 | 9,287 | 37,901 | 61,457 | 102,157 | 416,911 | 1,402,337 | 15,425,707 |
| -1 | -11 | -37 | -151 | -251 | -407 | -1,661 | -2,761 | -5,587 | -9,287 | -37,901 | -61,457 | -102,157 | -416,911 | -1,402,337 | -15,425,707 |
