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 56,565,509, 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 | 56,565,509 | |
| -1 | -56,565,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,565,509.
Example:
1 x 56,565,509 = 56,565,509
and
-1 x -56,565,509 = 56,565,509
Notice both answers equal 56,565,509
With that explanation out of the way, let's continue. Next, we take the number 56,565,509 and divide it by 2:
56,565,509 ÷ 2 = 28,282,754.5
If the quotient is a whole number, then 2 and 28,282,754.5 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 | 56,565,509 | |
| -1 | -56,565,509 |
Now, we try dividing 56,565,509 by 3:
56,565,509 ÷ 3 = 18,855,169.6667
If the quotient is a whole number, then 3 and 18,855,169.6667 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 | 56,565,509 | |
| -1 | -56,565,509 |
Let's try dividing by 4:
56,565,509 ÷ 4 = 14,141,377.25
If the quotient is a whole number, then 4 and 14,141,377.25 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 | 56,565,509 | |
| -1 | 56,565,509 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 56,509 | 395,563 | 621,599 | 734,617 | 4,351,193 | 5,142,319 | 8,080,787 | 56,565,509 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -56,509 | -395,563 | -621,599 | -734,617 | -4,351,193 | -5,142,319 | -8,080,787 | -56,565,509 |
