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 242,431,441, 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 | 242,431,441 | |
| -1 | -242,431,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,431,441.
Example:
1 x 242,431,441 = 242,431,441
and
-1 x -242,431,441 = 242,431,441
Notice both answers equal 242,431,441
With that explanation out of the way, let's continue. Next, we take the number 242,431,441 and divide it by 2:
242,431,441 ÷ 2 = 121,215,720.5
If the quotient is a whole number, then 2 and 121,215,720.5 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 | 242,431,441 | |
| -1 | -242,431,441 |
Now, we try dividing 242,431,441 by 3:
242,431,441 ÷ 3 = 80,810,480.3333
If the quotient is a whole number, then 3 and 80,810,480.3333 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 | 242,431,441 | |
| -1 | -242,431,441 |
Let's try dividing by 4:
242,431,441 ÷ 4 = 60,607,860.25
If the quotient is a whole number, then 4 and 60,607,860.25 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 | 242,431,441 | |
| -1 | 242,431,441 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 257 | 1,799 | 4,369 | 7,927 | 30,583 | 55,489 | 134,759 | 943,313 | 2,037,239 | 14,260,673 | 34,633,063 | 242,431,441 |
| -1 | -7 | -17 | -119 | -257 | -1,799 | -4,369 | -7,927 | -30,583 | -55,489 | -134,759 | -943,313 | -2,037,239 | -14,260,673 | -34,633,063 | -242,431,441 |
