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 117,756,265, 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 | 117,756,265 | |
| -1 | -117,756,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,756,265.
Example:
1 x 117,756,265 = 117,756,265
and
-1 x -117,756,265 = 117,756,265
Notice both answers equal 117,756,265
With that explanation out of the way, let's continue. Next, we take the number 117,756,265 and divide it by 2:
117,756,265 ÷ 2 = 58,878,132.5
If the quotient is a whole number, then 2 and 58,878,132.5 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 | 117,756,265 | |
| -1 | -117,756,265 |
Now, we try dividing 117,756,265 by 3:
117,756,265 ÷ 3 = 39,252,088.3333
If the quotient is a whole number, then 3 and 39,252,088.3333 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 | 117,756,265 | |
| -1 | -117,756,265 |
Let's try dividing by 4:
117,756,265 ÷ 4 = 29,439,066.25
If the quotient is a whole number, then 4 and 29,439,066.25 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 | 117,756,265 | |
| -1 | 117,756,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 223 | 1,115 | 2,453 | 9,601 | 12,265 | 48,005 | 105,611 | 528,055 | 2,141,023 | 10,705,115 | 23,551,253 | 117,756,265 |
| -1 | -5 | -11 | -55 | -223 | -1,115 | -2,453 | -9,601 | -12,265 | -48,005 | -105,611 | -528,055 | -2,141,023 | -10,705,115 | -23,551,253 | -117,756,265 |
