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 115,678,247, 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 | 115,678,247 | |
| -1 | -115,678,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,678,247.
Example:
1 x 115,678,247 = 115,678,247
and
-1 x -115,678,247 = 115,678,247
Notice both answers equal 115,678,247
With that explanation out of the way, let's continue. Next, we take the number 115,678,247 and divide it by 2:
115,678,247 ÷ 2 = 57,839,123.5
If the quotient is a whole number, then 2 and 57,839,123.5 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 | 115,678,247 | |
| -1 | -115,678,247 |
Now, we try dividing 115,678,247 by 3:
115,678,247 ÷ 3 = 38,559,415.6667
If the quotient is a whole number, then 3 and 38,559,415.6667 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 | 115,678,247 | |
| -1 | -115,678,247 |
Let's try dividing by 4:
115,678,247 ÷ 4 = 28,919,561.75
If the quotient is a whole number, then 4 and 28,919,561.75 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 | 115,678,247 | |
| -1 | 115,678,247 |
If you did it right, you will end up with this table:
| 1 | 23 | 67 | 271 | 277 | 1,541 | 6,233 | 6,371 | 18,157 | 18,559 | 75,067 | 417,611 | 426,857 | 1,726,541 | 5,029,489 | 115,678,247 |
| -1 | -23 | -67 | -271 | -277 | -1,541 | -6,233 | -6,371 | -18,157 | -18,559 | -75,067 | -417,611 | -426,857 | -1,726,541 | -5,029,489 | -115,678,247 |
