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 117,670,091, 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 | 117,670,091 | |
| -1 | -117,670,091 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,670,091.
Example:
1 x 117,670,091 = 117,670,091
and
-1 x -117,670,091 = 117,670,091
Notice both answers equal 117,670,091
With that explanation out of the way, let's continue. Next, we take the number 117,670,091 and divide it by 2:
117,670,091 ÷ 2 = 58,835,045.5
If the quotient is a whole number, then 2 and 58,835,045.5 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 | 117,670,091 | |
| -1 | -117,670,091 |
Now, we try dividing 117,670,091 by 3:
117,670,091 ÷ 3 = 39,223,363.6667
If the quotient is a whole number, then 3 and 39,223,363.6667 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 | 117,670,091 | |
| -1 | -117,670,091 |
Let's try dividing by 4:
117,670,091 ÷ 4 = 29,417,522.75
If the quotient is a whole number, then 4 and 29,417,522.75 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 | 117,670,091 | |
| -1 | 117,670,091 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 181 | 1,267 | 1,991 | 8,443 | 13,937 | 59,101 | 92,873 | 650,111 | 1,528,183 | 10,697,281 | 16,810,013 | 117,670,091 |
| -1 | -7 | -11 | -77 | -181 | -1,267 | -1,991 | -8,443 | -13,937 | -59,101 | -92,873 | -650,111 | -1,528,183 | -10,697,281 | -16,810,013 | -117,670,091 |
