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 331,233,145, 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 | 331,233,145 | |
| -1 | -331,233,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,233,145.
Example:
1 x 331,233,145 = 331,233,145
and
-1 x -331,233,145 = 331,233,145
Notice both answers equal 331,233,145
With that explanation out of the way, let's continue. Next, we take the number 331,233,145 and divide it by 2:
331,233,145 ÷ 2 = 165,616,572.5
If the quotient is a whole number, then 2 and 165,616,572.5 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 | 331,233,145 | |
| -1 | -331,233,145 |
Now, we try dividing 331,233,145 by 3:
331,233,145 ÷ 3 = 110,411,048.3333
If the quotient is a whole number, then 3 and 110,411,048.3333 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 | 331,233,145 | |
| -1 | -331,233,145 |
Let's try dividing by 4:
331,233,145 ÷ 4 = 82,808,286.25
If the quotient is a whole number, then 4 and 82,808,286.25 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 | 331,233,145 | |
| -1 | 331,233,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 127 | 359 | 635 | 1,453 | 1,795 | 7,265 | 45,593 | 184,531 | 227,965 | 521,627 | 922,655 | 2,608,135 | 66,246,629 | 331,233,145 |
| -1 | -5 | -127 | -359 | -635 | -1,453 | -1,795 | -7,265 | -45,593 | -184,531 | -227,965 | -521,627 | -922,655 | -2,608,135 | -66,246,629 | -331,233,145 |
