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 243,324,431, 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 | 243,324,431 | |
| -1 | -243,324,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 243,324,431.
Example:
1 x 243,324,431 = 243,324,431
and
-1 x -243,324,431 = 243,324,431
Notice both answers equal 243,324,431
With that explanation out of the way, let's continue. Next, we take the number 243,324,431 and divide it by 2:
243,324,431 ÷ 2 = 121,662,215.5
If the quotient is a whole number, then 2 and 121,662,215.5 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 | 243,324,431 | |
| -1 | -243,324,431 |
Now, we try dividing 243,324,431 by 3:
243,324,431 ÷ 3 = 81,108,143.6667
If the quotient is a whole number, then 3 and 81,108,143.6667 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 | 243,324,431 | |
| -1 | -243,324,431 |
Let's try dividing by 4:
243,324,431 ÷ 4 = 60,831,107.75
If the quotient is a whole number, then 4 and 60,831,107.75 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 | 243,324,431 | |
| -1 | 243,324,431 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 53 | 133 | 371 | 1,007 | 7,049 | 34,519 | 241,633 | 655,861 | 1,829,507 | 4,591,027 | 12,806,549 | 34,760,633 | 243,324,431 |
| -1 | -7 | -19 | -53 | -133 | -371 | -1,007 | -7,049 | -34,519 | -241,633 | -655,861 | -1,829,507 | -4,591,027 | -12,806,549 | -34,760,633 | -243,324,431 |
