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 56,557,715, 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 | 56,557,715 | |
| -1 | -56,557,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,557,715.
Example:
1 x 56,557,715 = 56,557,715
and
-1 x -56,557,715 = 56,557,715
Notice both answers equal 56,557,715
With that explanation out of the way, let's continue. Next, we take the number 56,557,715 and divide it by 2:
56,557,715 ÷ 2 = 28,278,857.5
If the quotient is a whole number, then 2 and 28,278,857.5 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 | 56,557,715 | |
| -1 | -56,557,715 |
Now, we try dividing 56,557,715 by 3:
56,557,715 ÷ 3 = 18,852,571.6667
If the quotient is a whole number, then 3 and 18,852,571.6667 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 | 56,557,715 | |
| -1 | -56,557,715 |
Let's try dividing by 4:
56,557,715 ÷ 4 = 14,139,428.75
If the quotient is a whole number, then 4 and 14,139,428.75 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 | 56,557,715 | |
| -1 | 56,557,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 197 | 335 | 857 | 985 | 4,285 | 13,199 | 57,419 | 65,995 | 168,829 | 287,095 | 844,145 | 11,311,543 | 56,557,715 |
| -1 | -5 | -67 | -197 | -335 | -857 | -985 | -4,285 | -13,199 | -57,419 | -65,995 | -168,829 | -287,095 | -844,145 | -11,311,543 | -56,557,715 |
