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 332,120,551, 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 | 332,120,551 | |
| -1 | -332,120,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 332,120,551.
Example:
1 x 332,120,551 = 332,120,551
and
-1 x -332,120,551 = 332,120,551
Notice both answers equal 332,120,551
With that explanation out of the way, let's continue. Next, we take the number 332,120,551 and divide it by 2:
332,120,551 ÷ 2 = 166,060,275.5
If the quotient is a whole number, then 2 and 166,060,275.5 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 | 332,120,551 | |
| -1 | -332,120,551 |
Now, we try dividing 332,120,551 by 3:
332,120,551 ÷ 3 = 110,706,850.3333
If the quotient is a whole number, then 3 and 110,706,850.3333 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 | 332,120,551 | |
| -1 | -332,120,551 |
Let's try dividing by 4:
332,120,551 ÷ 4 = 83,030,137.75
If the quotient is a whole number, then 4 and 83,030,137.75 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 | 332,120,551 | |
| -1 | 332,120,551 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 146,891 | 1,028,237 | 2,497,147 | 2,790,929 | 17,480,029 | 19,536,503 | 47,445,793 | 332,120,551 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -146,891 | -1,028,237 | -2,497,147 | -2,790,929 | -17,480,029 | -19,536,503 | -47,445,793 | -332,120,551 |
