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 242,305, 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 | 242,305 | |
| -1 | -242,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,305.
Example:
1 x 242,305 = 242,305
and
-1 x -242,305 = 242,305
Notice both answers equal 242,305
With that explanation out of the way, let's continue. Next, we take the number 242,305 and divide it by 2:
242,305 ÷ 2 = 121,152.5
If the quotient is a whole number, then 2 and 121,152.5 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 | 242,305 | |
| -1 | -242,305 |
Now, we try dividing 242,305 by 3:
242,305 ÷ 3 = 80,768.3333
If the quotient is a whole number, then 3 and 80,768.3333 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 | 242,305 | |
| -1 | -242,305 |
Let's try dividing by 4:
242,305 ÷ 4 = 60,576.25
If the quotient is a whole number, then 4 and 60,576.25 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 | 242,305 | |
| -1 | 242,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 43 | 49 | 115 | 161 | 215 | 245 | 301 | 805 | 989 | 1,127 | 1,505 | 2,107 | 4,945 | 5,635 | 6,923 | 10,535 | 34,615 | 48,461 | 242,305 |
| -1 | -5 | -7 | -23 | -35 | -43 | -49 | -115 | -161 | -215 | -245 | -301 | -805 | -989 | -1,127 | -1,505 | -2,107 | -4,945 | -5,635 | -6,923 | -10,535 | -34,615 | -48,461 | -242,305 |
