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 3,083,185, 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 | 3,083,185 | |
| -1 | -3,083,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,083,185.
Example:
1 x 3,083,185 = 3,083,185
and
-1 x -3,083,185 = 3,083,185
Notice both answers equal 3,083,185
With that explanation out of the way, let's continue. Next, we take the number 3,083,185 and divide it by 2:
3,083,185 ÷ 2 = 1,541,592.5
If the quotient is a whole number, then 2 and 1,541,592.5 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 | 3,083,185 | |
| -1 | -3,083,185 |
Now, we try dividing 3,083,185 by 3:
3,083,185 ÷ 3 = 1,027,728.3333
If the quotient is a whole number, then 3 and 1,027,728.3333 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 | 3,083,185 | |
| -1 | -3,083,185 |
Let's try dividing by 4:
3,083,185 ÷ 4 = 770,796.25
If the quotient is a whole number, then 4 and 770,796.25 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 | 3,083,185 | |
| -1 | 3,083,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 137 | 643 | 685 | 959 | 3,215 | 4,501 | 4,795 | 22,505 | 88,091 | 440,455 | 616,637 | 3,083,185 |
| -1 | -5 | -7 | -35 | -137 | -643 | -685 | -959 | -3,215 | -4,501 | -4,795 | -22,505 | -88,091 | -440,455 | -616,637 | -3,083,185 |
