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 242,566,483, 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 | 242,566,483 | |
| -1 | -242,566,483 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,566,483.
Example:
1 x 242,566,483 = 242,566,483
and
-1 x -242,566,483 = 242,566,483
Notice both answers equal 242,566,483
With that explanation out of the way, let's continue. Next, we take the number 242,566,483 and divide it by 2:
242,566,483 ÷ 2 = 121,283,241.5
If the quotient is a whole number, then 2 and 121,283,241.5 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 | 242,566,483 | |
| -1 | -242,566,483 |
Now, we try dividing 242,566,483 by 3:
242,566,483 ÷ 3 = 80,855,494.3333
If the quotient is a whole number, then 3 and 80,855,494.3333 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 | 242,566,483 | |
| -1 | -242,566,483 |
Let's try dividing by 4:
242,566,483 ÷ 4 = 60,641,620.75
If the quotient is a whole number, then 4 and 60,641,620.75 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 | 242,566,483 | |
| -1 | 242,566,483 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 47 | 817 | 893 | 2,021 | 6,317 | 38,399 | 120,023 | 271,631 | 296,899 | 5,160,989 | 5,641,081 | 12,766,657 | 242,566,483 |
| -1 | -19 | -43 | -47 | -817 | -893 | -2,021 | -6,317 | -38,399 | -120,023 | -271,631 | -296,899 | -5,160,989 | -5,641,081 | -12,766,657 | -242,566,483 |
