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 56,206,565, 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 | 56,206,565 | |
| -1 | -56,206,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,206,565.
Example:
1 x 56,206,565 = 56,206,565
and
-1 x -56,206,565 = 56,206,565
Notice both answers equal 56,206,565
With that explanation out of the way, let's continue. Next, we take the number 56,206,565 and divide it by 2:
56,206,565 ÷ 2 = 28,103,282.5
If the quotient is a whole number, then 2 and 28,103,282.5 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 | 56,206,565 | |
| -1 | -56,206,565 |
Now, we try dividing 56,206,565 by 3:
56,206,565 ÷ 3 = 18,735,521.6667
If the quotient is a whole number, then 3 and 18,735,521.6667 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 | 56,206,565 | |
| -1 | -56,206,565 |
Let's try dividing by 4:
56,206,565 ÷ 4 = 14,051,641.25
If the quotient is a whole number, then 4 and 14,051,641.25 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 | 56,206,565 | |
| -1 | 56,206,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 107 | 155 | 535 | 3,317 | 3,389 | 16,585 | 16,945 | 105,059 | 362,623 | 525,295 | 1,813,115 | 11,241,313 | 56,206,565 |
| -1 | -5 | -31 | -107 | -155 | -535 | -3,317 | -3,389 | -16,585 | -16,945 | -105,059 | -362,623 | -525,295 | -1,813,115 | -11,241,313 | -56,206,565 |
