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 242,231,639, 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 | 242,231,639 | |
| -1 | -242,231,639 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,231,639.
Example:
1 x 242,231,639 = 242,231,639
and
-1 x -242,231,639 = 242,231,639
Notice both answers equal 242,231,639
With that explanation out of the way, let's continue. Next, we take the number 242,231,639 and divide it by 2:
242,231,639 ÷ 2 = 121,115,819.5
If the quotient is a whole number, then 2 and 121,115,819.5 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 | 242,231,639 | |
| -1 | -242,231,639 |
Now, we try dividing 242,231,639 by 3:
242,231,639 ÷ 3 = 80,743,879.6667
If the quotient is a whole number, then 3 and 80,743,879.6667 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 | 242,231,639 | |
| -1 | -242,231,639 |
Let's try dividing by 4:
242,231,639 ÷ 4 = 60,557,909.75
If the quotient is a whole number, then 4 and 60,557,909.75 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 | 242,231,639 | |
| -1 | 242,231,639 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 313 | 767 | 1,009 | 4,069 | 13,117 | 18,467 | 59,531 | 240,071 | 315,817 | 773,903 | 4,105,621 | 18,633,203 | 242,231,639 |
| -1 | -13 | -59 | -313 | -767 | -1,009 | -4,069 | -13,117 | -18,467 | -59,531 | -240,071 | -315,817 | -773,903 | -4,105,621 | -18,633,203 | -242,231,639 |
