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 7,952,917, 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 | 7,952,917 | |
| -1 | -7,952,917 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,952,917.
Example:
1 x 7,952,917 = 7,952,917
and
-1 x -7,952,917 = 7,952,917
Notice both answers equal 7,952,917
With that explanation out of the way, let's continue. Next, we take the number 7,952,917 and divide it by 2:
7,952,917 ÷ 2 = 3,976,458.5
If the quotient is a whole number, then 2 and 3,976,458.5 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 | 7,952,917 | |
| -1 | -7,952,917 |
Now, we try dividing 7,952,917 by 3:
7,952,917 ÷ 3 = 2,650,972.3333
If the quotient is a whole number, then 3 and 2,650,972.3333 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 | 7,952,917 | |
| -1 | -7,952,917 |
Let's try dividing by 4:
7,952,917 ÷ 4 = 1,988,229.25
If the quotient is a whole number, then 4 and 1,988,229.25 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 | 7,952,917 | |
| -1 | 7,952,917 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 47 | 161 | 329 | 1,051 | 1,081 | 7,357 | 7,567 | 24,173 | 49,397 | 169,211 | 345,779 | 1,136,131 | 7,952,917 |
| -1 | -7 | -23 | -47 | -161 | -329 | -1,051 | -1,081 | -7,357 | -7,567 | -24,173 | -49,397 | -169,211 | -345,779 | -1,136,131 | -7,952,917 |
