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 242,253,013, 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 | 242,253,013 | |
| -1 | -242,253,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,253,013.
Example:
1 x 242,253,013 = 242,253,013
and
-1 x -242,253,013 = 242,253,013
Notice both answers equal 242,253,013
With that explanation out of the way, let's continue. Next, we take the number 242,253,013 and divide it by 2:
242,253,013 ÷ 2 = 121,126,506.5
If the quotient is a whole number, then 2 and 121,126,506.5 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 | 242,253,013 | |
| -1 | -242,253,013 |
Now, we try dividing 242,253,013 by 3:
242,253,013 ÷ 3 = 80,751,004.3333
If the quotient is a whole number, then 3 and 80,751,004.3333 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 | 242,253,013 | |
| -1 | -242,253,013 |
Let's try dividing by 4:
242,253,013 ÷ 4 = 60,563,253.25
If the quotient is a whole number, then 4 and 60,563,253.25 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 | 242,253,013 | |
| -1 | 242,253,013 |
If you did it right, you will end up with this table:
| 1 | 43 | 83 | 103 | 659 | 3,569 | 4,429 | 8,549 | 28,337 | 54,697 | 67,877 | 367,607 | 2,351,971 | 2,918,711 | 5,633,791 | 242,253,013 |
| -1 | -43 | -83 | -103 | -659 | -3,569 | -4,429 | -8,549 | -28,337 | -54,697 | -67,877 | -367,607 | -2,351,971 | -2,918,711 | -5,633,791 | -242,253,013 |
