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 117,823,265, 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 | 117,823,265 | |
| -1 | -117,823,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,823,265.
Example:
1 x 117,823,265 = 117,823,265
and
-1 x -117,823,265 = 117,823,265
Notice both answers equal 117,823,265
With that explanation out of the way, let's continue. Next, we take the number 117,823,265 and divide it by 2:
117,823,265 ÷ 2 = 58,911,632.5
If the quotient is a whole number, then 2 and 58,911,632.5 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 | 117,823,265 | |
| -1 | -117,823,265 |
Now, we try dividing 117,823,265 by 3:
117,823,265 ÷ 3 = 39,274,421.6667
If the quotient is a whole number, then 3 and 39,274,421.6667 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 | 117,823,265 | |
| -1 | -117,823,265 |
Let's try dividing by 4:
117,823,265 ÷ 4 = 29,455,816.25
If the quotient is a whole number, then 4 and 29,455,816.25 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 | 117,823,265 | |
| -1 | 117,823,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 757 | 3,785 | 4,447 | 5,299 | 22,235 | 26,495 | 31,129 | 155,645 | 3,366,379 | 16,831,895 | 23,564,653 | 117,823,265 |
| -1 | -5 | -7 | -35 | -757 | -3,785 | -4,447 | -5,299 | -22,235 | -26,495 | -31,129 | -155,645 | -3,366,379 | -16,831,895 | -23,564,653 | -117,823,265 |
