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 242,033,099, 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 | 242,033,099 | |
| -1 | -242,033,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,033,099.
Example:
1 x 242,033,099 = 242,033,099
and
-1 x -242,033,099 = 242,033,099
Notice both answers equal 242,033,099
With that explanation out of the way, let's continue. Next, we take the number 242,033,099 and divide it by 2:
242,033,099 ÷ 2 = 121,016,549.5
If the quotient is a whole number, then 2 and 121,016,549.5 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 | 242,033,099 | |
| -1 | -242,033,099 |
Now, we try dividing 242,033,099 by 3:
242,033,099 ÷ 3 = 80,677,699.6667
If the quotient is a whole number, then 3 and 80,677,699.6667 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 | 242,033,099 | |
| -1 | -242,033,099 |
Let's try dividing by 4:
242,033,099 ÷ 4 = 60,508,274.75
If the quotient is a whole number, then 4 and 60,508,274.75 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 | 242,033,099 | |
| -1 | 242,033,099 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 191 | 539 | 1,337 | 2,101 | 2,351 | 9,359 | 14,707 | 16,457 | 25,861 | 102,949 | 115,199 | 181,027 | 449,041 | 1,267,189 | 3,143,287 | 4,939,451 | 22,003,009 | 34,576,157 | 242,033,099 |
| -1 | -7 | -11 | -49 | -77 | -191 | -539 | -1,337 | -2,101 | -2,351 | -9,359 | -14,707 | -16,457 | -25,861 | -102,949 | -115,199 | -181,027 | -449,041 | -1,267,189 | -3,143,287 | -4,939,451 | -22,003,009 | -34,576,157 | -242,033,099 |
