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 4,080,775, 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 | 4,080,775 | |
| -1 | -4,080,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,080,775.
Example:
1 x 4,080,775 = 4,080,775
and
-1 x -4,080,775 = 4,080,775
Notice both answers equal 4,080,775
With that explanation out of the way, let's continue. Next, we take the number 4,080,775 and divide it by 2:
4,080,775 ÷ 2 = 2,040,387.5
If the quotient is a whole number, then 2 and 2,040,387.5 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 | 4,080,775 | |
| -1 | -4,080,775 |
Now, we try dividing 4,080,775 by 3:
4,080,775 ÷ 3 = 1,360,258.3333
If the quotient is a whole number, then 3 and 1,360,258.3333 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 | 4,080,775 | |
| -1 | -4,080,775 |
Let's try dividing by 4:
4,080,775 ÷ 4 = 1,020,193.75
If the quotient is a whole number, then 4 and 1,020,193.75 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 | 4,080,775 | |
| -1 | 4,080,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 47 | 115 | 151 | 235 | 575 | 755 | 1,081 | 1,175 | 3,473 | 3,775 | 5,405 | 7,097 | 17,365 | 27,025 | 35,485 | 86,825 | 163,231 | 177,425 | 816,155 | 4,080,775 |
| -1 | -5 | -23 | -25 | -47 | -115 | -151 | -235 | -575 | -755 | -1,081 | -1,175 | -3,473 | -3,775 | -5,405 | -7,097 | -17,365 | -27,025 | -35,485 | -86,825 | -163,231 | -177,425 | -816,155 | -4,080,775 |
