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 100,456,135, 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 | 100,456,135 | |
| -1 | -100,456,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,456,135.
Example:
1 x 100,456,135 = 100,456,135
and
-1 x -100,456,135 = 100,456,135
Notice both answers equal 100,456,135
With that explanation out of the way, let's continue. Next, we take the number 100,456,135 and divide it by 2:
100,456,135 ÷ 2 = 50,228,067.5
If the quotient is a whole number, then 2 and 50,228,067.5 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 | 100,456,135 | |
| -1 | -100,456,135 |
Now, we try dividing 100,456,135 by 3:
100,456,135 ÷ 3 = 33,485,378.3333
If the quotient is a whole number, then 3 and 33,485,378.3333 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 | 100,456,135 | |
| -1 | -100,456,135 |
Let's try dividing by 4:
100,456,135 ÷ 4 = 25,114,033.75
If the quotient is a whole number, then 4 and 25,114,033.75 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 | 100,456,135 | |
| -1 | 100,456,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 169 | 247 | 845 | 1,235 | 3,211 | 6,257 | 16,055 | 31,285 | 81,341 | 118,883 | 406,705 | 594,415 | 1,057,433 | 1,545,479 | 5,287,165 | 7,727,395 | 20,091,227 | 100,456,135 |
| -1 | -5 | -13 | -19 | -65 | -95 | -169 | -247 | -845 | -1,235 | -3,211 | -6,257 | -16,055 | -31,285 | -81,341 | -118,883 | -406,705 | -594,415 | -1,057,433 | -1,545,479 | -5,287,165 | -7,727,395 | -20,091,227 | -100,456,135 |
