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 115,445,015, 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 | 115,445,015 | |
| -1 | -115,445,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,445,015.
Example:
1 x 115,445,015 = 115,445,015
and
-1 x -115,445,015 = 115,445,015
Notice both answers equal 115,445,015
With that explanation out of the way, let's continue. Next, we take the number 115,445,015 and divide it by 2:
115,445,015 ÷ 2 = 57,722,507.5
If the quotient is a whole number, then 2 and 57,722,507.5 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 | 115,445,015 | |
| -1 | -115,445,015 |
Now, we try dividing 115,445,015 by 3:
115,445,015 ÷ 3 = 38,481,671.6667
If the quotient is a whole number, then 3 and 38,481,671.6667 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 | 115,445,015 | |
| -1 | -115,445,015 |
Let's try dividing by 4:
115,445,015 ÷ 4 = 28,861,253.75
If the quotient is a whole number, then 4 and 28,861,253.75 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 | 115,445,015 | |
| -1 | 115,445,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 89 | 445 | 623 | 3,115 | 37,061 | 185,305 | 259,427 | 1,297,135 | 3,298,429 | 16,492,145 | 23,089,003 | 115,445,015 |
| -1 | -5 | -7 | -35 | -89 | -445 | -623 | -3,115 | -37,061 | -185,305 | -259,427 | -1,297,135 | -3,298,429 | -16,492,145 | -23,089,003 | -115,445,015 |
