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 56,760,145, 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 | 56,760,145 | |
| -1 | -56,760,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,760,145.
Example:
1 x 56,760,145 = 56,760,145
and
-1 x -56,760,145 = 56,760,145
Notice both answers equal 56,760,145
With that explanation out of the way, let's continue. Next, we take the number 56,760,145 and divide it by 2:
56,760,145 ÷ 2 = 28,380,072.5
If the quotient is a whole number, then 2 and 28,380,072.5 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 | 56,760,145 | |
| -1 | -56,760,145 |
Now, we try dividing 56,760,145 by 3:
56,760,145 ÷ 3 = 18,920,048.3333
If the quotient is a whole number, then 3 and 18,920,048.3333 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 | 56,760,145 | |
| -1 | -56,760,145 |
Let's try dividing by 4:
56,760,145 ÷ 4 = 14,190,036.25
If the quotient is a whole number, then 4 and 14,190,036.25 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 | 56,760,145 | |
| -1 | 56,760,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 151 | 755 | 1,963 | 5,783 | 9,815 | 28,915 | 75,179 | 375,895 | 873,233 | 4,366,165 | 11,352,029 | 56,760,145 |
| -1 | -5 | -13 | -65 | -151 | -755 | -1,963 | -5,783 | -9,815 | -28,915 | -75,179 | -375,895 | -873,233 | -4,366,165 | -11,352,029 | -56,760,145 |
