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 153,255,115, 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 | 153,255,115 | |
| -1 | -153,255,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,255,115.
Example:
1 x 153,255,115 = 153,255,115
and
-1 x -153,255,115 = 153,255,115
Notice both answers equal 153,255,115
With that explanation out of the way, let's continue. Next, we take the number 153,255,115 and divide it by 2:
153,255,115 ÷ 2 = 76,627,557.5
If the quotient is a whole number, then 2 and 76,627,557.5 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 | 153,255,115 | |
| -1 | -153,255,115 |
Now, we try dividing 153,255,115 by 3:
153,255,115 ÷ 3 = 51,085,038.3333
If the quotient is a whole number, then 3 and 51,085,038.3333 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 | 153,255,115 | |
| -1 | -153,255,115 |
Let's try dividing by 4:
153,255,115 ÷ 4 = 38,313,778.75
If the quotient is a whole number, then 4 and 38,313,778.75 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 | 153,255,115 | |
| -1 | 153,255,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 169 | 293 | 619 | 845 | 1,465 | 3,095 | 3,809 | 8,047 | 19,045 | 40,235 | 49,517 | 104,611 | 181,367 | 247,585 | 523,055 | 906,835 | 2,357,771 | 11,788,855 | 30,651,023 | 153,255,115 |
| -1 | -5 | -13 | -65 | -169 | -293 | -619 | -845 | -1,465 | -3,095 | -3,809 | -8,047 | -19,045 | -40,235 | -49,517 | -104,611 | -181,367 | -247,585 | -523,055 | -906,835 | -2,357,771 | -11,788,855 | -30,651,023 | -153,255,115 |
