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 3,885,775, 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 | 3,885,775 | |
| -1 | -3,885,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,885,775.
Example:
1 x 3,885,775 = 3,885,775
and
-1 x -3,885,775 = 3,885,775
Notice both answers equal 3,885,775
With that explanation out of the way, let's continue. Next, we take the number 3,885,775 and divide it by 2:
3,885,775 ÷ 2 = 1,942,887.5
If the quotient is a whole number, then 2 and 1,942,887.5 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 | 3,885,775 | |
| -1 | -3,885,775 |
Now, we try dividing 3,885,775 by 3:
3,885,775 ÷ 3 = 1,295,258.3333
If the quotient is a whole number, then 3 and 1,295,258.3333 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 | 3,885,775 | |
| -1 | -3,885,775 |
Let's try dividing by 4:
3,885,775 ÷ 4 = 971,443.75
If the quotient is a whole number, then 4 and 971,443.75 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 | 3,885,775 | |
| -1 | 3,885,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 41 | 85 | 205 | 223 | 425 | 697 | 1,025 | 1,115 | 3,485 | 3,791 | 5,575 | 9,143 | 17,425 | 18,955 | 45,715 | 94,775 | 155,431 | 228,575 | 777,155 | 3,885,775 |
| -1 | -5 | -17 | -25 | -41 | -85 | -205 | -223 | -425 | -697 | -1,025 | -1,115 | -3,485 | -3,791 | -5,575 | -9,143 | -17,425 | -18,955 | -45,715 | -94,775 | -155,431 | -228,575 | -777,155 | -3,885,775 |
