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 130,315,255, 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 | 130,315,255 | |
| -1 | -130,315,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,315,255.
Example:
1 x 130,315,255 = 130,315,255
and
-1 x -130,315,255 = 130,315,255
Notice both answers equal 130,315,255
With that explanation out of the way, let's continue. Next, we take the number 130,315,255 and divide it by 2:
130,315,255 ÷ 2 = 65,157,627.5
If the quotient is a whole number, then 2 and 65,157,627.5 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 | 130,315,255 | |
| -1 | -130,315,255 |
Now, we try dividing 130,315,255 by 3:
130,315,255 ÷ 3 = 43,438,418.3333
If the quotient is a whole number, then 3 and 43,438,418.3333 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 | 130,315,255 | |
| -1 | -130,315,255 |
Let's try dividing by 4:
130,315,255 ÷ 4 = 32,578,813.75
If the quotient is a whole number, then 4 and 32,578,813.75 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 | 130,315,255 | |
| -1 | 130,315,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 49 | 235 | 245 | 329 | 1,645 | 2,303 | 11,317 | 11,515 | 56,585 | 79,219 | 396,095 | 531,899 | 554,533 | 2,659,495 | 2,772,665 | 3,723,293 | 18,616,465 | 26,063,051 | 130,315,255 |
| -1 | -5 | -7 | -35 | -47 | -49 | -235 | -245 | -329 | -1,645 | -2,303 | -11,317 | -11,515 | -56,585 | -79,219 | -396,095 | -531,899 | -554,533 | -2,659,495 | -2,772,665 | -3,723,293 | -18,616,465 | -26,063,051 | -130,315,255 |
