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 242,103,647, 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 | 242,103,647 | |
| -1 | -242,103,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,103,647.
Example:
1 x 242,103,647 = 242,103,647
and
-1 x -242,103,647 = 242,103,647
Notice both answers equal 242,103,647
With that explanation out of the way, let's continue. Next, we take the number 242,103,647 and divide it by 2:
242,103,647 ÷ 2 = 121,051,823.5
If the quotient is a whole number, then 2 and 121,051,823.5 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 | 242,103,647 | |
| -1 | -242,103,647 |
Now, we try dividing 242,103,647 by 3:
242,103,647 ÷ 3 = 80,701,215.6667
If the quotient is a whole number, then 3 and 80,701,215.6667 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 | 242,103,647 | |
| -1 | -242,103,647 |
Let's try dividing by 4:
242,103,647 ÷ 4 = 60,525,911.75
If the quotient is a whole number, then 4 and 60,525,911.75 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 | 242,103,647 | |
| -1 | 242,103,647 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 419 | 697 | 829 | 7,123 | 14,093 | 17,179 | 33,989 | 292,043 | 347,351 | 577,813 | 5,904,967 | 14,241,391 | 242,103,647 |
| -1 | -17 | -41 | -419 | -697 | -829 | -7,123 | -14,093 | -17,179 | -33,989 | -292,043 | -347,351 | -577,813 | -5,904,967 | -14,241,391 | -242,103,647 |
