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 3,083,815, 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 | 3,083,815 | |
| -1 | -3,083,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,083,815.
Example:
1 x 3,083,815 = 3,083,815
and
-1 x -3,083,815 = 3,083,815
Notice both answers equal 3,083,815
With that explanation out of the way, let's continue. Next, we take the number 3,083,815 and divide it by 2:
3,083,815 ÷ 2 = 1,541,907.5
If the quotient is a whole number, then 2 and 1,541,907.5 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 | 3,083,815 | |
| -1 | -3,083,815 |
Now, we try dividing 3,083,815 by 3:
3,083,815 ÷ 3 = 1,027,938.3333
If the quotient is a whole number, then 3 and 1,027,938.3333 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 | 3,083,815 | |
| -1 | -3,083,815 |
Let's try dividing by 4:
3,083,815 ÷ 4 = 770,953.75
If the quotient is a whole number, then 4 and 770,953.75 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 | 3,083,815 | |
| -1 | 3,083,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 49 | 205 | 245 | 287 | 307 | 1,435 | 1,535 | 2,009 | 2,149 | 10,045 | 10,745 | 12,587 | 15,043 | 62,935 | 75,215 | 88,109 | 440,545 | 616,763 | 3,083,815 |
| -1 | -5 | -7 | -35 | -41 | -49 | -205 | -245 | -287 | -307 | -1,435 | -1,535 | -2,009 | -2,149 | -10,045 | -10,745 | -12,587 | -15,043 | -62,935 | -75,215 | -88,109 | -440,545 | -616,763 | -3,083,815 |
