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 242,425,105, 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 | 242,425,105 | |
| -1 | -242,425,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,425,105.
Example:
1 x 242,425,105 = 242,425,105
and
-1 x -242,425,105 = 242,425,105
Notice both answers equal 242,425,105
With that explanation out of the way, let's continue. Next, we take the number 242,425,105 and divide it by 2:
242,425,105 ÷ 2 = 121,212,552.5
If the quotient is a whole number, then 2 and 121,212,552.5 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 | 242,425,105 | |
| -1 | -242,425,105 |
Now, we try dividing 242,425,105 by 3:
242,425,105 ÷ 3 = 80,808,368.3333
If the quotient is a whole number, then 3 and 80,808,368.3333 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 | 242,425,105 | |
| -1 | -242,425,105 |
Let's try dividing by 4:
242,425,105 ÷ 4 = 60,606,276.25
If the quotient is a whole number, then 4 and 60,606,276.25 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 | 242,425,105 | |
| -1 | 242,425,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 443 | 2,215 | 5,759 | 8,419 | 28,795 | 42,095 | 109,447 | 547,235 | 3,729,617 | 18,648,085 | 48,485,021 | 242,425,105 |
| -1 | -5 | -13 | -65 | -443 | -2,215 | -5,759 | -8,419 | -28,795 | -42,095 | -109,447 | -547,235 | -3,729,617 | -18,648,085 | -48,485,021 | -242,425,105 |
