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 383,731,825, 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 | 383,731,825 | |
| -1 | -383,731,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 383,731,825.
Example:
1 x 383,731,825 = 383,731,825
and
-1 x -383,731,825 = 383,731,825
Notice both answers equal 383,731,825
With that explanation out of the way, let's continue. Next, we take the number 383,731,825 and divide it by 2:
383,731,825 ÷ 2 = 191,865,912.5
If the quotient is a whole number, then 2 and 191,865,912.5 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 | 383,731,825 | |
| -1 | -383,731,825 |
Now, we try dividing 383,731,825 by 3:
383,731,825 ÷ 3 = 127,910,608.3333
If the quotient is a whole number, then 3 and 127,910,608.3333 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 | 383,731,825 | |
| -1 | -383,731,825 |
Let's try dividing by 4:
383,731,825 ÷ 4 = 95,932,956.25
If the quotient is a whole number, then 4 and 95,932,956.25 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 | 383,731,825 | |
| -1 | 383,731,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 83 | 101 | 415 | 505 | 1,831 | 2,075 | 2,525 | 8,383 | 9,155 | 41,915 | 45,775 | 151,973 | 184,931 | 209,575 | 759,865 | 924,655 | 3,799,325 | 4,623,275 | 15,349,273 | 76,746,365 | 383,731,825 |
| -1 | -5 | -25 | -83 | -101 | -415 | -505 | -1,831 | -2,075 | -2,525 | -8,383 | -9,155 | -41,915 | -45,775 | -151,973 | -184,931 | -209,575 | -759,865 | -924,655 | -3,799,325 | -4,623,275 | -15,349,273 | -76,746,365 | -383,731,825 |
