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 101,117,185, 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 | 101,117,185 | |
| -1 | -101,117,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,117,185.
Example:
1 x 101,117,185 = 101,117,185
and
-1 x -101,117,185 = 101,117,185
Notice both answers equal 101,117,185
With that explanation out of the way, let's continue. Next, we take the number 101,117,185 and divide it by 2:
101,117,185 ÷ 2 = 50,558,592.5
If the quotient is a whole number, then 2 and 50,558,592.5 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 | 101,117,185 | |
| -1 | -101,117,185 |
Now, we try dividing 101,117,185 by 3:
101,117,185 ÷ 3 = 33,705,728.3333
If the quotient is a whole number, then 3 and 33,705,728.3333 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 | 101,117,185 | |
| -1 | -101,117,185 |
Let's try dividing by 4:
101,117,185 ÷ 4 = 25,279,296.25
If the quotient is a whole number, then 4 and 25,279,296.25 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 | 101,117,185 | |
| -1 | 101,117,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 859 | 1,811 | 4,295 | 9,055 | 11,167 | 23,543 | 55,835 | 117,715 | 1,555,649 | 7,778,245 | 20,223,437 | 101,117,185 |
| -1 | -5 | -13 | -65 | -859 | -1,811 | -4,295 | -9,055 | -11,167 | -23,543 | -55,835 | -117,715 | -1,555,649 | -7,778,245 | -20,223,437 | -101,117,185 |
