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 242,344,031, 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 | 242,344,031 | |
| -1 | -242,344,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,344,031.
Example:
1 x 242,344,031 = 242,344,031
and
-1 x -242,344,031 = 242,344,031
Notice both answers equal 242,344,031
With that explanation out of the way, let's continue. Next, we take the number 242,344,031 and divide it by 2:
242,344,031 ÷ 2 = 121,172,015.5
If the quotient is a whole number, then 2 and 121,172,015.5 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 | 242,344,031 | |
| -1 | -242,344,031 |
Now, we try dividing 242,344,031 by 3:
242,344,031 ÷ 3 = 80,781,343.6667
If the quotient is a whole number, then 3 and 80,781,343.6667 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 | 242,344,031 | |
| -1 | -242,344,031 |
Let's try dividing by 4:
242,344,031 ÷ 4 = 60,586,007.75
If the quotient is a whole number, then 4 and 60,586,007.75 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 | 242,344,031 | |
| -1 | 242,344,031 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 353 | 437 | 1,571 | 6,707 | 8,119 | 29,849 | 36,133 | 154,261 | 554,563 | 686,527 | 10,536,697 | 12,754,949 | 242,344,031 |
| -1 | -19 | -23 | -353 | -437 | -1,571 | -6,707 | -8,119 | -29,849 | -36,133 | -154,261 | -554,563 | -686,527 | -10,536,697 | -12,754,949 | -242,344,031 |
