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 56,555,705, 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 | 56,555,705 | |
| -1 | -56,555,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,555,705.
Example:
1 x 56,555,705 = 56,555,705
and
-1 x -56,555,705 = 56,555,705
Notice both answers equal 56,555,705
With that explanation out of the way, let's continue. Next, we take the number 56,555,705 and divide it by 2:
56,555,705 ÷ 2 = 28,277,852.5
If the quotient is a whole number, then 2 and 28,277,852.5 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 | 56,555,705 | |
| -1 | -56,555,705 |
Now, we try dividing 56,555,705 by 3:
56,555,705 ÷ 3 = 18,851,901.6667
If the quotient is a whole number, then 3 and 18,851,901.6667 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 | 56,555,705 | |
| -1 | -56,555,705 |
Let's try dividing by 4:
56,555,705 ÷ 4 = 14,138,926.25
If the quotient is a whole number, then 4 and 14,138,926.25 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 | 56,555,705 | |
| -1 | 56,555,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 79 | 335 | 395 | 2,137 | 5,293 | 10,685 | 26,465 | 143,179 | 168,823 | 715,895 | 844,115 | 11,311,141 | 56,555,705 |
| -1 | -5 | -67 | -79 | -335 | -395 | -2,137 | -5,293 | -10,685 | -26,465 | -143,179 | -168,823 | -715,895 | -844,115 | -11,311,141 | -56,555,705 |
