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 242,215,127, 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 | 242,215,127 | |
| -1 | -242,215,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,215,127.
Example:
1 x 242,215,127 = 242,215,127
and
-1 x -242,215,127 = 242,215,127
Notice both answers equal 242,215,127
With that explanation out of the way, let's continue. Next, we take the number 242,215,127 and divide it by 2:
242,215,127 ÷ 2 = 121,107,563.5
If the quotient is a whole number, then 2 and 121,107,563.5 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 | 242,215,127 | |
| -1 | -242,215,127 |
Now, we try dividing 242,215,127 by 3:
242,215,127 ÷ 3 = 80,738,375.6667
If the quotient is a whole number, then 3 and 80,738,375.6667 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 | 242,215,127 | |
| -1 | -242,215,127 |
Let's try dividing by 4:
242,215,127 ÷ 4 = 60,553,781.75
If the quotient is a whole number, then 4 and 60,553,781.75 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 | 242,215,127 | |
| -1 | 242,215,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 967 | 3,253 | 6,769 | 10,637 | 22,771 | 35,783 | 74,459 | 250,481 | 3,145,651 | 22,019,557 | 34,602,161 | 242,215,127 |
| -1 | -7 | -11 | -77 | -967 | -3,253 | -6,769 | -10,637 | -22,771 | -35,783 | -74,459 | -250,481 | -3,145,651 | -22,019,557 | -34,602,161 | -242,215,127 |
