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 115,252,151, 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 | 115,252,151 | |
| -1 | -115,252,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,252,151.
Example:
1 x 115,252,151 = 115,252,151
and
-1 x -115,252,151 = 115,252,151
Notice both answers equal 115,252,151
With that explanation out of the way, let's continue. Next, we take the number 115,252,151 and divide it by 2:
115,252,151 ÷ 2 = 57,626,075.5
If the quotient is a whole number, then 2 and 57,626,075.5 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 | 115,252,151 | |
| -1 | -115,252,151 |
Now, we try dividing 115,252,151 by 3:
115,252,151 ÷ 3 = 38,417,383.6667
If the quotient is a whole number, then 3 and 38,417,383.6667 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 | 115,252,151 | |
| -1 | -115,252,151 |
Let's try dividing by 4:
115,252,151 ÷ 4 = 28,813,037.75
If the quotient is a whole number, then 4 and 28,813,037.75 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 | 115,252,151 | |
| -1 | 115,252,151 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 373 | 1,193 | 2,611 | 8,351 | 13,801 | 44,141 | 96,607 | 308,987 | 444,989 | 3,114,923 | 16,464,593 | 115,252,151 |
| -1 | -7 | -37 | -259 | -373 | -1,193 | -2,611 | -8,351 | -13,801 | -44,141 | -96,607 | -308,987 | -444,989 | -3,114,923 | -16,464,593 | -115,252,151 |
