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 242,002,201, 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 | 242,002,201 | |
| -1 | -242,002,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,002,201.
Example:
1 x 242,002,201 = 242,002,201
and
-1 x -242,002,201 = 242,002,201
Notice both answers equal 242,002,201
With that explanation out of the way, let's continue. Next, we take the number 242,002,201 and divide it by 2:
242,002,201 ÷ 2 = 121,001,100.5
If the quotient is a whole number, then 2 and 121,001,100.5 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 | 242,002,201 | |
| -1 | -242,002,201 |
Now, we try dividing 242,002,201 by 3:
242,002,201 ÷ 3 = 80,667,400.3333
If the quotient is a whole number, then 3 and 80,667,400.3333 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 | 242,002,201 | |
| -1 | -242,002,201 |
Let's try dividing by 4:
242,002,201 ÷ 4 = 60,500,550.25
If the quotient is a whole number, then 4 and 60,500,550.25 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 | 242,002,201 | |
| -1 | 242,002,201 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 79 | 329 | 553 | 3,713 | 9,311 | 25,991 | 65,177 | 437,617 | 735,569 | 3,063,319 | 5,148,983 | 34,571,743 | 242,002,201 |
| -1 | -7 | -47 | -79 | -329 | -553 | -3,713 | -9,311 | -25,991 | -65,177 | -437,617 | -735,569 | -3,063,319 | -5,148,983 | -34,571,743 | -242,002,201 |
