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 3,850,775, 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 | 3,850,775 | |
| -1 | -3,850,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,850,775.
Example:
1 x 3,850,775 = 3,850,775
and
-1 x -3,850,775 = 3,850,775
Notice both answers equal 3,850,775
With that explanation out of the way, let's continue. Next, we take the number 3,850,775 and divide it by 2:
3,850,775 ÷ 2 = 1,925,387.5
If the quotient is a whole number, then 2 and 1,925,387.5 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 | 3,850,775 | |
| -1 | -3,850,775 |
Now, we try dividing 3,850,775 by 3:
3,850,775 ÷ 3 = 1,283,591.6667
If the quotient is a whole number, then 3 and 1,283,591.6667 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 | 3,850,775 | |
| -1 | -3,850,775 |
Let's try dividing by 4:
3,850,775 ÷ 4 = 962,693.75
If the quotient is a whole number, then 4 and 962,693.75 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 | 3,850,775 | |
| -1 | 3,850,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 37 | 115 | 181 | 185 | 575 | 851 | 905 | 925 | 4,163 | 4,255 | 4,525 | 6,697 | 20,815 | 21,275 | 33,485 | 104,075 | 154,031 | 167,425 | 770,155 | 3,850,775 |
| -1 | -5 | -23 | -25 | -37 | -115 | -181 | -185 | -575 | -851 | -905 | -925 | -4,163 | -4,255 | -4,525 | -6,697 | -20,815 | -21,275 | -33,485 | -104,075 | -154,031 | -167,425 | -770,155 | -3,850,775 |
