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 242,354,225, 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 | 242,354,225 | |
| -1 | -242,354,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,354,225.
Example:
1 x 242,354,225 = 242,354,225
and
-1 x -242,354,225 = 242,354,225
Notice both answers equal 242,354,225
With that explanation out of the way, let's continue. Next, we take the number 242,354,225 and divide it by 2:
242,354,225 ÷ 2 = 121,177,112.5
If the quotient is a whole number, then 2 and 121,177,112.5 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 | 242,354,225 | |
| -1 | -242,354,225 |
Now, we try dividing 242,354,225 by 3:
242,354,225 ÷ 3 = 80,784,741.6667
If the quotient is a whole number, then 3 and 80,784,741.6667 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 | 242,354,225 | |
| -1 | -242,354,225 |
Let's try dividing by 4:
242,354,225 ÷ 4 = 60,588,556.25
If the quotient is a whole number, then 4 and 60,588,556.25 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 | 242,354,225 | |
| -1 | 242,354,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 79 | 277 | 395 | 443 | 1,385 | 1,975 | 2,215 | 6,925 | 11,075 | 21,883 | 34,997 | 109,415 | 122,711 | 174,985 | 547,075 | 613,555 | 874,925 | 3,067,775 | 9,694,169 | 48,470,845 | 242,354,225 |
| -1 | -5 | -25 | -79 | -277 | -395 | -443 | -1,385 | -1,975 | -2,215 | -6,925 | -11,075 | -21,883 | -34,997 | -109,415 | -122,711 | -174,985 | -547,075 | -613,555 | -874,925 | -3,067,775 | -9,694,169 | -48,470,845 | -242,354,225 |
