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 115,250,525, 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 | 115,250,525 | |
| -1 | -115,250,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,250,525.
Example:
1 x 115,250,525 = 115,250,525
and
-1 x -115,250,525 = 115,250,525
Notice both answers equal 115,250,525
With that explanation out of the way, let's continue. Next, we take the number 115,250,525 and divide it by 2:
115,250,525 ÷ 2 = 57,625,262.5
If the quotient is a whole number, then 2 and 57,625,262.5 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 | 115,250,525 | |
| -1 | -115,250,525 |
Now, we try dividing 115,250,525 by 3:
115,250,525 ÷ 3 = 38,416,841.6667
If the quotient is a whole number, then 3 and 38,416,841.6667 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 | 115,250,525 | |
| -1 | -115,250,525 |
Let's try dividing by 4:
115,250,525 ÷ 4 = 28,812,631.25
If the quotient is a whole number, then 4 and 28,812,631.25 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 | 115,250,525 | |
| -1 | 115,250,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 131 | 325 | 655 | 1,703 | 2,707 | 3,275 | 8,515 | 13,535 | 35,191 | 42,575 | 67,675 | 175,955 | 354,617 | 879,775 | 1,773,085 | 4,610,021 | 8,865,425 | 23,050,105 | 115,250,525 |
| -1 | -5 | -13 | -25 | -65 | -131 | -325 | -655 | -1,703 | -2,707 | -3,275 | -8,515 | -13,535 | -35,191 | -42,575 | -67,675 | -175,955 | -354,617 | -879,775 | -1,773,085 | -4,610,021 | -8,865,425 | -23,050,105 | -115,250,525 |
