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 56,716,765, 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 | 56,716,765 | |
| -1 | -56,716,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,716,765.
Example:
1 x 56,716,765 = 56,716,765
and
-1 x -56,716,765 = 56,716,765
Notice both answers equal 56,716,765
With that explanation out of the way, let's continue. Next, we take the number 56,716,765 and divide it by 2:
56,716,765 ÷ 2 = 28,358,382.5
If the quotient is a whole number, then 2 and 28,358,382.5 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 | 56,716,765 | |
| -1 | -56,716,765 |
Now, we try dividing 56,716,765 by 3:
56,716,765 ÷ 3 = 18,905,588.3333
If the quotient is a whole number, then 3 and 18,905,588.3333 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 | 56,716,765 | |
| -1 | -56,716,765 |
Let's try dividing by 4:
56,716,765 ÷ 4 = 14,179,191.25
If the quotient is a whole number, then 4 and 14,179,191.25 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 | 56,716,765 | |
| -1 | 56,716,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 33,071 | 165,355 | 231,497 | 1,157,485 | 1,620,479 | 8,102,395 | 11,343,353 | 56,716,765 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -33,071 | -165,355 | -231,497 | -1,157,485 | -1,620,479 | -8,102,395 | -11,343,353 | -56,716,765 |
