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 56,205,515, 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 | 56,205,515 | |
| -1 | -56,205,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,205,515.
Example:
1 x 56,205,515 = 56,205,515
and
-1 x -56,205,515 = 56,205,515
Notice both answers equal 56,205,515
With that explanation out of the way, let's continue. Next, we take the number 56,205,515 and divide it by 2:
56,205,515 ÷ 2 = 28,102,757.5
If the quotient is a whole number, then 2 and 28,102,757.5 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 | 56,205,515 | |
| -1 | -56,205,515 |
Now, we try dividing 56,205,515 by 3:
56,205,515 ÷ 3 = 18,735,171.6667
If the quotient is a whole number, then 3 and 18,735,171.6667 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 | 56,205,515 | |
| -1 | -56,205,515 |
Let's try dividing by 4:
56,205,515 ÷ 4 = 14,051,378.75
If the quotient is a whole number, then 4 and 14,051,378.75 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 | 56,205,515 | |
| -1 | 56,205,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 43 | 95 | 215 | 817 | 4,085 | 13,759 | 68,795 | 261,421 | 591,637 | 1,307,105 | 2,958,185 | 11,241,103 | 56,205,515 |
| -1 | -5 | -19 | -43 | -95 | -215 | -817 | -4,085 | -13,759 | -68,795 | -261,421 | -591,637 | -1,307,105 | -2,958,185 | -11,241,103 | -56,205,515 |
