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 96,101,915, 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 | 96,101,915 | |
| -1 | -96,101,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 96,101,915.
Example:
1 x 96,101,915 = 96,101,915
and
-1 x -96,101,915 = 96,101,915
Notice both answers equal 96,101,915
With that explanation out of the way, let's continue. Next, we take the number 96,101,915 and divide it by 2:
96,101,915 ÷ 2 = 48,050,957.5
If the quotient is a whole number, then 2 and 48,050,957.5 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 | 96,101,915 | |
| -1 | -96,101,915 |
Now, we try dividing 96,101,915 by 3:
96,101,915 ÷ 3 = 32,033,971.6667
If the quotient is a whole number, then 3 and 32,033,971.6667 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 | 96,101,915 | |
| -1 | -96,101,915 |
Let's try dividing by 4:
96,101,915 ÷ 4 = 24,025,478.75
If the quotient is a whole number, then 4 and 24,025,478.75 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 | 96,101,915 | |
| -1 | 96,101,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 211,213 | 1,056,065 | 1,478,491 | 2,745,769 | 7,392,455 | 13,728,845 | 19,220,383 | 96,101,915 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -211,213 | -1,056,065 | -1,478,491 | -2,745,769 | -7,392,455 | -13,728,845 | -19,220,383 | -96,101,915 |
