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 117,501,671, 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 | 117,501,671 | |
| -1 | -117,501,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,501,671.
Example:
1 x 117,501,671 = 117,501,671
and
-1 x -117,501,671 = 117,501,671
Notice both answers equal 117,501,671
With that explanation out of the way, let's continue. Next, we take the number 117,501,671 and divide it by 2:
117,501,671 ÷ 2 = 58,750,835.5
If the quotient is a whole number, then 2 and 58,750,835.5 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 | 117,501,671 | |
| -1 | -117,501,671 |
Now, we try dividing 117,501,671 by 3:
117,501,671 ÷ 3 = 39,167,223.6667
If the quotient is a whole number, then 3 and 39,167,223.6667 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 | 117,501,671 | |
| -1 | -117,501,671 |
Let's try dividing by 4:
117,501,671 ÷ 4 = 29,375,417.75
If the quotient is a whole number, then 4 and 29,375,417.75 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 | 117,501,671 | |
| -1 | 117,501,671 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 43 | 119 | 301 | 731 | 5,117 | 22,963 | 160,741 | 390,371 | 987,409 | 2,732,597 | 6,911,863 | 16,785,953 | 117,501,671 |
| -1 | -7 | -17 | -43 | -119 | -301 | -731 | -5,117 | -22,963 | -160,741 | -390,371 | -987,409 | -2,732,597 | -6,911,863 | -16,785,953 | -117,501,671 |
