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 242,545,235, 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 | 242,545,235 | |
| -1 | -242,545,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,545,235.
Example:
1 x 242,545,235 = 242,545,235
and
-1 x -242,545,235 = 242,545,235
Notice both answers equal 242,545,235
With that explanation out of the way, let's continue. Next, we take the number 242,545,235 and divide it by 2:
242,545,235 ÷ 2 = 121,272,617.5
If the quotient is a whole number, then 2 and 121,272,617.5 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 | 242,545,235 | |
| -1 | -242,545,235 |
Now, we try dividing 242,545,235 by 3:
242,545,235 ÷ 3 = 80,848,411.6667
If the quotient is a whole number, then 3 and 80,848,411.6667 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 | 242,545,235 | |
| -1 | -242,545,235 |
Let's try dividing by 4:
242,545,235 ÷ 4 = 60,636,308.75
If the quotient is a whole number, then 4 and 60,636,308.75 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 | 242,545,235 | |
| -1 | 242,545,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 127 | 635 | 2,921 | 14,605 | 16,607 | 83,035 | 381,961 | 1,909,805 | 2,109,089 | 10,545,445 | 48,509,047 | 242,545,235 |
| -1 | -5 | -23 | -115 | -127 | -635 | -2,921 | -14,605 | -16,607 | -83,035 | -381,961 | -1,909,805 | -2,109,089 | -10,545,445 | -48,509,047 | -242,545,235 |
