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 56,256,791, 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 | 56,256,791 | |
| -1 | -56,256,791 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,256,791.
Example:
1 x 56,256,791 = 56,256,791
and
-1 x -56,256,791 = 56,256,791
Notice both answers equal 56,256,791
With that explanation out of the way, let's continue. Next, we take the number 56,256,791 and divide it by 2:
56,256,791 ÷ 2 = 28,128,395.5
If the quotient is a whole number, then 2 and 28,128,395.5 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 | 56,256,791 | |
| -1 | -56,256,791 |
Now, we try dividing 56,256,791 by 3:
56,256,791 ÷ 3 = 18,752,263.6667
If the quotient is a whole number, then 3 and 18,752,263.6667 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 | 56,256,791 | |
| -1 | -56,256,791 |
Let's try dividing by 4:
56,256,791 ÷ 4 = 14,064,197.75
If the quotient is a whole number, then 4 and 14,064,197.75 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 | 56,256,791 | |
| -1 | 56,256,791 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 181 | 389 | 799 | 3,077 | 6,613 | 8,507 | 18,283 | 70,409 | 144,619 | 310,811 | 1,196,953 | 3,309,223 | 56,256,791 |
| -1 | -17 | -47 | -181 | -389 | -799 | -3,077 | -6,613 | -8,507 | -18,283 | -70,409 | -144,619 | -310,811 | -1,196,953 | -3,309,223 | -56,256,791 |
