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 3,022,415, 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 | 3,022,415 | |
| -1 | -3,022,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,022,415.
Example:
1 x 3,022,415 = 3,022,415
and
-1 x -3,022,415 = 3,022,415
Notice both answers equal 3,022,415
With that explanation out of the way, let's continue. Next, we take the number 3,022,415 and divide it by 2:
3,022,415 ÷ 2 = 1,511,207.5
If the quotient is a whole number, then 2 and 1,511,207.5 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 | 3,022,415 | |
| -1 | -3,022,415 |
Now, we try dividing 3,022,415 by 3:
3,022,415 ÷ 3 = 1,007,471.6667
If the quotient is a whole number, then 3 and 1,007,471.6667 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 | 3,022,415 | |
| -1 | -3,022,415 |
Let's try dividing by 4:
3,022,415 ÷ 4 = 755,603.75
If the quotient is a whole number, then 4 and 755,603.75 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 | 3,022,415 | |
| -1 | 3,022,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 179 | 307 | 895 | 1,535 | 1,969 | 3,377 | 9,845 | 16,885 | 54,953 | 274,765 | 604,483 | 3,022,415 |
| -1 | -5 | -11 | -55 | -179 | -307 | -895 | -1,535 | -1,969 | -3,377 | -9,845 | -16,885 | -54,953 | -274,765 | -604,483 | -3,022,415 |
