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 56,913,745, 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 | 56,913,745 | |
| -1 | -56,913,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,913,745.
Example:
1 x 56,913,745 = 56,913,745
and
-1 x -56,913,745 = 56,913,745
Notice both answers equal 56,913,745
With that explanation out of the way, let's continue. Next, we take the number 56,913,745 and divide it by 2:
56,913,745 ÷ 2 = 28,456,872.5
If the quotient is a whole number, then 2 and 28,456,872.5 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 | 56,913,745 | |
| -1 | -56,913,745 |
Now, we try dividing 56,913,745 by 3:
56,913,745 ÷ 3 = 18,971,248.3333
If the quotient is a whole number, then 3 and 18,971,248.3333 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 | 56,913,745 | |
| -1 | -56,913,745 |
Let's try dividing by 4:
56,913,745 ÷ 4 = 14,228,436.25
If the quotient is a whole number, then 4 and 14,228,436.25 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 | 56,913,745 | |
| -1 | 56,913,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 233 | 245 | 997 | 1,165 | 1,631 | 4,985 | 6,979 | 8,155 | 11,417 | 34,895 | 48,853 | 57,085 | 232,301 | 244,265 | 1,161,505 | 1,626,107 | 8,130,535 | 11,382,749 | 56,913,745 |
| -1 | -5 | -7 | -35 | -49 | -233 | -245 | -997 | -1,165 | -1,631 | -4,985 | -6,979 | -8,155 | -11,417 | -34,895 | -48,853 | -57,085 | -232,301 | -244,265 | -1,161,505 | -1,626,107 | -8,130,535 | -11,382,749 | -56,913,745 |
