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 56,681,807, 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 | 56,681,807 | |
| -1 | -56,681,807 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,681,807.
Example:
1 x 56,681,807 = 56,681,807
and
-1 x -56,681,807 = 56,681,807
Notice both answers equal 56,681,807
With that explanation out of the way, let's continue. Next, we take the number 56,681,807 and divide it by 2:
56,681,807 ÷ 2 = 28,340,903.5
If the quotient is a whole number, then 2 and 28,340,903.5 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 | 56,681,807 | |
| -1 | -56,681,807 |
Now, we try dividing 56,681,807 by 3:
56,681,807 ÷ 3 = 18,893,935.6667
If the quotient is a whole number, then 3 and 18,893,935.6667 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 | 56,681,807 | |
| -1 | -56,681,807 |
Let's try dividing by 4:
56,681,807 ÷ 4 = 14,170,451.75
If the quotient is a whole number, then 4 and 14,170,451.75 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 | 56,681,807 | |
| -1 | 56,681,807 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 91 | 133 | 247 | 1,729 | 32,783 | 229,481 | 426,179 | 622,877 | 2,983,253 | 4,360,139 | 8,097,401 | 56,681,807 |
| -1 | -7 | -13 | -19 | -91 | -133 | -247 | -1,729 | -32,783 | -229,481 | -426,179 | -622,877 | -2,983,253 | -4,360,139 | -8,097,401 | -56,681,807 |
