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 331,102,409, 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 | 331,102,409 | |
| -1 | -331,102,409 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,102,409.
Example:
1 x 331,102,409 = 331,102,409
and
-1 x -331,102,409 = 331,102,409
Notice both answers equal 331,102,409
With that explanation out of the way, let's continue. Next, we take the number 331,102,409 and divide it by 2:
331,102,409 ÷ 2 = 165,551,204.5
If the quotient is a whole number, then 2 and 165,551,204.5 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 | 331,102,409 | |
| -1 | -331,102,409 |
Now, we try dividing 331,102,409 by 3:
331,102,409 ÷ 3 = 110,367,469.6667
If the quotient is a whole number, then 3 and 110,367,469.6667 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 | 331,102,409 | |
| -1 | -331,102,409 |
Let's try dividing by 4:
331,102,409 ÷ 4 = 82,775,602.25
If the quotient is a whole number, then 4 and 82,775,602.25 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 | 331,102,409 | |
| -1 | 331,102,409 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 523 | 737 | 859 | 5,753 | 9,449 | 35,041 | 57,553 | 385,451 | 449,257 | 633,083 | 4,941,827 | 30,100,219 | 331,102,409 |
| -1 | -11 | -67 | -523 | -737 | -859 | -5,753 | -9,449 | -35,041 | -57,553 | -385,451 | -449,257 | -633,083 | -4,941,827 | -30,100,219 | -331,102,409 |
