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 332,416,381, 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 | 332,416,381 | |
| -1 | -332,416,381 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 332,416,381.
Example:
1 x 332,416,381 = 332,416,381
and
-1 x -332,416,381 = 332,416,381
Notice both answers equal 332,416,381
With that explanation out of the way, let's continue. Next, we take the number 332,416,381 and divide it by 2:
332,416,381 ÷ 2 = 166,208,190.5
If the quotient is a whole number, then 2 and 166,208,190.5 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 | 332,416,381 | |
| -1 | -332,416,381 |
Now, we try dividing 332,416,381 by 3:
332,416,381 ÷ 3 = 110,805,460.3333
If the quotient is a whole number, then 3 and 110,805,460.3333 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 | 332,416,381 | |
| -1 | -332,416,381 |
Let's try dividing by 4:
332,416,381 ÷ 4 = 83,104,095.25
If the quotient is a whole number, then 4 and 83,104,095.25 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 | 332,416,381 | |
| -1 | 332,416,381 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 97 | 209 | 361 | 863 | 1,067 | 1,843 | 3,971 | 9,493 | 16,397 | 20,273 | 35,017 | 83,711 | 180,367 | 311,543 | 385,187 | 920,821 | 1,590,509 | 3,426,973 | 17,495,599 | 30,219,671 | 332,416,381 |
| -1 | -11 | -19 | -97 | -209 | -361 | -863 | -1,067 | -1,843 | -3,971 | -9,493 | -16,397 | -20,273 | -35,017 | -83,711 | -180,367 | -311,543 | -385,187 | -920,821 | -1,590,509 | -3,426,973 | -17,495,599 | -30,219,671 | -332,416,381 |
