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 241,330,397, 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 | 241,330,397 | |
| -1 | -241,330,397 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 241,330,397.
Example:
1 x 241,330,397 = 241,330,397
and
-1 x -241,330,397 = 241,330,397
Notice both answers equal 241,330,397
With that explanation out of the way, let's continue. Next, we take the number 241,330,397 and divide it by 2:
241,330,397 ÷ 2 = 120,665,198.5
If the quotient is a whole number, then 2 and 120,665,198.5 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 | 241,330,397 | |
| -1 | -241,330,397 |
Now, we try dividing 241,330,397 by 3:
241,330,397 ÷ 3 = 80,443,465.6667
If the quotient is a whole number, then 3 and 80,443,465.6667 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 | 241,330,397 | |
| -1 | -241,330,397 |
Let's try dividing by 4:
241,330,397 ÷ 4 = 60,332,599.25
If the quotient is a whole number, then 4 and 60,332,599.25 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 | 241,330,397 | |
| -1 | 241,330,397 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 673 | 4,657 | 4,711 | 7,403 | 32,599 | 51,227 | 51,821 | 358,589 | 3,134,161 | 21,939,127 | 34,475,771 | 241,330,397 |
| -1 | -7 | -11 | -77 | -673 | -4,657 | -4,711 | -7,403 | -32,599 | -51,227 | -51,821 | -358,589 | -3,134,161 | -21,939,127 | -34,475,771 | -241,330,397 |
