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 255,076,955, 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 | 255,076,955 | |
| -1 | -255,076,955 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 255,076,955.
Example:
1 x 255,076,955 = 255,076,955
and
-1 x -255,076,955 = 255,076,955
Notice both answers equal 255,076,955
With that explanation out of the way, let's continue. Next, we take the number 255,076,955 and divide it by 2:
255,076,955 ÷ 2 = 127,538,477.5
If the quotient is a whole number, then 2 and 127,538,477.5 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 | 255,076,955 | |
| -1 | -255,076,955 |
Now, we try dividing 255,076,955 by 3:
255,076,955 ÷ 3 = 85,025,651.6667
If the quotient is a whole number, then 3 and 85,025,651.6667 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 | 255,076,955 | |
| -1 | -255,076,955 |
Let's try dividing by 4:
255,076,955 ÷ 4 = 63,769,238.75
If the quotient is a whole number, then 4 and 63,769,238.75 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 | 255,076,955 | |
| -1 | 255,076,955 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 491 | 2,455 | 3,437 | 14,843 | 17,185 | 74,215 | 103,901 | 519,505 | 7,287,913 | 36,439,565 | 51,015,391 | 255,076,955 |
| -1 | -5 | -7 | -35 | -491 | -2,455 | -3,437 | -14,843 | -17,185 | -74,215 | -103,901 | -519,505 | -7,287,913 | -36,439,565 | -51,015,391 | -255,076,955 |
