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 101,132,015, 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 | 101,132,015 | |
| -1 | -101,132,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,132,015.
Example:
1 x 101,132,015 = 101,132,015
and
-1 x -101,132,015 = 101,132,015
Notice both answers equal 101,132,015
With that explanation out of the way, let's continue. Next, we take the number 101,132,015 and divide it by 2:
101,132,015 ÷ 2 = 50,566,007.5
If the quotient is a whole number, then 2 and 50,566,007.5 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 | 101,132,015 | |
| -1 | -101,132,015 |
Now, we try dividing 101,132,015 by 3:
101,132,015 ÷ 3 = 33,710,671.6667
If the quotient is a whole number, then 3 and 33,710,671.6667 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 | 101,132,015 | |
| -1 | -101,132,015 |
Let's try dividing by 4:
101,132,015 ÷ 4 = 25,283,003.75
If the quotient is a whole number, then 4 and 25,283,003.75 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 | 101,132,015 | |
| -1 | 101,132,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 337 | 1,277 | 1,685 | 6,385 | 15,839 | 60,019 | 79,195 | 300,095 | 430,349 | 2,151,745 | 20,226,403 | 101,132,015 |
| -1 | -5 | -47 | -235 | -337 | -1,277 | -1,685 | -6,385 | -15,839 | -60,019 | -79,195 | -300,095 | -430,349 | -2,151,745 | -20,226,403 | -101,132,015 |
