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 55,727,255, 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 | 55,727,255 | |
| -1 | -55,727,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,727,255.
Example:
1 x 55,727,255 = 55,727,255
and
-1 x -55,727,255 = 55,727,255
Notice both answers equal 55,727,255
With that explanation out of the way, let's continue. Next, we take the number 55,727,255 and divide it by 2:
55,727,255 ÷ 2 = 27,863,627.5
If the quotient is a whole number, then 2 and 27,863,627.5 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 | 55,727,255 | |
| -1 | -55,727,255 |
Now, we try dividing 55,727,255 by 3:
55,727,255 ÷ 3 = 18,575,751.6667
If the quotient is a whole number, then 3 and 18,575,751.6667 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 | 55,727,255 | |
| -1 | -55,727,255 |
Let's try dividing by 4:
55,727,255 ÷ 4 = 13,931,813.75
If the quotient is a whole number, then 4 and 13,931,813.75 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 | 55,727,255 | |
| -1 | 55,727,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 163 | 505 | 677 | 815 | 3,385 | 16,463 | 68,377 | 82,315 | 110,351 | 341,885 | 551,755 | 11,145,451 | 55,727,255 |
| -1 | -5 | -101 | -163 | -505 | -677 | -815 | -3,385 | -16,463 | -68,377 | -82,315 | -110,351 | -341,885 | -551,755 | -11,145,451 | -55,727,255 |
