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 180,365,255, 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 | 180,365,255 | |
| -1 | -180,365,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 180,365,255.
Example:
1 x 180,365,255 = 180,365,255
and
-1 x -180,365,255 = 180,365,255
Notice both answers equal 180,365,255
With that explanation out of the way, let's continue. Next, we take the number 180,365,255 and divide it by 2:
180,365,255 ÷ 2 = 90,182,627.5
If the quotient is a whole number, then 2 and 90,182,627.5 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 | 180,365,255 | |
| -1 | -180,365,255 |
Now, we try dividing 180,365,255 by 3:
180,365,255 ÷ 3 = 60,121,751.6667
If the quotient is a whole number, then 3 and 60,121,751.6667 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 | 180,365,255 | |
| -1 | -180,365,255 |
Let's try dividing by 4:
180,365,255 ÷ 4 = 45,091,313.75
If the quotient is a whole number, then 4 and 45,091,313.75 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 | 180,365,255 | |
| -1 | 180,365,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 193 | 965 | 1,351 | 6,755 | 26,701 | 133,505 | 186,907 | 934,535 | 5,153,293 | 25,766,465 | 36,073,051 | 180,365,255 |
| -1 | -5 | -7 | -35 | -193 | -965 | -1,351 | -6,755 | -26,701 | -133,505 | -186,907 | -934,535 | -5,153,293 | -25,766,465 | -36,073,051 | -180,365,255 |
