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 366,571,255, 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 | 366,571,255 | |
| -1 | -366,571,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 366,571,255.
Example:
1 x 366,571,255 = 366,571,255
and
-1 x -366,571,255 = 366,571,255
Notice both answers equal 366,571,255
With that explanation out of the way, let's continue. Next, we take the number 366,571,255 and divide it by 2:
366,571,255 ÷ 2 = 183,285,627.5
If the quotient is a whole number, then 2 and 183,285,627.5 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 | 366,571,255 | |
| -1 | -366,571,255 |
Now, we try dividing 366,571,255 by 3:
366,571,255 ÷ 3 = 122,190,418.3333
If the quotient is a whole number, then 3 and 122,190,418.3333 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 | 366,571,255 | |
| -1 | -366,571,255 |
Let's try dividing by 4:
366,571,255 ÷ 4 = 91,642,813.75
If the quotient is a whole number, then 4 and 91,642,813.75 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 | 366,571,255 | |
| -1 | 366,571,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 941 | 4,583 | 4,705 | 15,997 | 22,915 | 77,911 | 79,985 | 389,555 | 4,312,603 | 21,563,015 | 73,314,251 | 366,571,255 |
| -1 | -5 | -17 | -85 | -941 | -4,583 | -4,705 | -15,997 | -22,915 | -77,911 | -79,985 | -389,555 | -4,312,603 | -21,563,015 | -73,314,251 | -366,571,255 |
