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 56,760,721, 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 | 56,760,721 | |
| -1 | -56,760,721 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,760,721.
Example:
1 x 56,760,721 = 56,760,721
and
-1 x -56,760,721 = 56,760,721
Notice both answers equal 56,760,721
With that explanation out of the way, let's continue. Next, we take the number 56,760,721 and divide it by 2:
56,760,721 ÷ 2 = 28,380,360.5
If the quotient is a whole number, then 2 and 28,380,360.5 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 | 56,760,721 | |
| -1 | -56,760,721 |
Now, we try dividing 56,760,721 by 3:
56,760,721 ÷ 3 = 18,920,240.3333
If the quotient is a whole number, then 3 and 18,920,240.3333 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 | 56,760,721 | |
| -1 | -56,760,721 |
Let's try dividing by 4:
56,760,721 ÷ 4 = 14,190,180.25
If the quotient is a whole number, then 4 and 14,190,180.25 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 | 56,760,721 | |
| -1 | 56,760,721 |
If you did it right, you will end up with this table:
| 1 | 31 | 53 | 179 | 193 | 1,643 | 5,549 | 5,983 | 9,487 | 10,229 | 34,547 | 294,097 | 317,099 | 1,070,957 | 1,830,991 | 56,760,721 |
| -1 | -31 | -53 | -179 | -193 | -1,643 | -5,549 | -5,983 | -9,487 | -10,229 | -34,547 | -294,097 | -317,099 | -1,070,957 | -1,830,991 | -56,760,721 |
