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 115,033,807, 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 | 115,033,807 | |
| -1 | -115,033,807 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,033,807.
Example:
1 x 115,033,807 = 115,033,807
and
-1 x -115,033,807 = 115,033,807
Notice both answers equal 115,033,807
With that explanation out of the way, let's continue. Next, we take the number 115,033,807 and divide it by 2:
115,033,807 ÷ 2 = 57,516,903.5
If the quotient is a whole number, then 2 and 57,516,903.5 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 | 115,033,807 | |
| -1 | -115,033,807 |
Now, we try dividing 115,033,807 by 3:
115,033,807 ÷ 3 = 38,344,602.3333
If the quotient is a whole number, then 3 and 38,344,602.3333 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 | 115,033,807 | |
| -1 | -115,033,807 |
Let's try dividing by 4:
115,033,807 ÷ 4 = 28,758,451.75
If the quotient is a whole number, then 4 and 28,758,451.75 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 | 115,033,807 | |
| -1 | 115,033,807 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 239 | 1,673 | 2,371 | 6,931 | 16,597 | 48,517 | 68,759 | 481,313 | 566,669 | 3,966,683 | 16,433,401 | 115,033,807 |
| -1 | -7 | -29 | -203 | -239 | -1,673 | -2,371 | -6,931 | -16,597 | -48,517 | -68,759 | -481,313 | -566,669 | -3,966,683 | -16,433,401 | -115,033,807 |
