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 3,024,215, 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 | 3,024,215 | |
| -1 | -3,024,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,024,215.
Example:
1 x 3,024,215 = 3,024,215
and
-1 x -3,024,215 = 3,024,215
Notice both answers equal 3,024,215
With that explanation out of the way, let's continue. Next, we take the number 3,024,215 and divide it by 2:
3,024,215 ÷ 2 = 1,512,107.5
If the quotient is a whole number, then 2 and 1,512,107.5 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 | 3,024,215 | |
| -1 | -3,024,215 |
Now, we try dividing 3,024,215 by 3:
3,024,215 ÷ 3 = 1,008,071.6667
If the quotient is a whole number, then 3 and 1,008,071.6667 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 | 3,024,215 | |
| -1 | -3,024,215 |
Let's try dividing by 4:
3,024,215 ÷ 4 = 756,053.75
If the quotient is a whole number, then 4 and 756,053.75 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 | 3,024,215 | |
| -1 | 3,024,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 47 | 85 | 235 | 757 | 799 | 3,785 | 3,995 | 12,869 | 35,579 | 64,345 | 177,895 | 604,843 | 3,024,215 |
| -1 | -5 | -17 | -47 | -85 | -235 | -757 | -799 | -3,785 | -3,995 | -12,869 | -35,579 | -64,345 | -177,895 | -604,843 | -3,024,215 |
