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 2,022,215, 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 | 2,022,215 | |
| -1 | -2,022,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,022,215.
Example:
1 x 2,022,215 = 2,022,215
and
-1 x -2,022,215 = 2,022,215
Notice both answers equal 2,022,215
With that explanation out of the way, let's continue. Next, we take the number 2,022,215 and divide it by 2:
2,022,215 ÷ 2 = 1,011,107.5
If the quotient is a whole number, then 2 and 1,011,107.5 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 | 2,022,215 | |
| -1 | -2,022,215 |
Now, we try dividing 2,022,215 by 3:
2,022,215 ÷ 3 = 674,071.6667
If the quotient is a whole number, then 3 and 674,071.6667 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 | 2,022,215 | |
| -1 | -2,022,215 |
Let's try dividing by 4:
2,022,215 ÷ 4 = 505,553.75
If the quotient is a whole number, then 4 and 505,553.75 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 | 2,022,215 | |
| -1 | 2,022,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 53 | 65 | 265 | 587 | 689 | 2,935 | 3,445 | 7,631 | 31,111 | 38,155 | 155,555 | 404,443 | 2,022,215 |
| -1 | -5 | -13 | -53 | -65 | -265 | -587 | -689 | -2,935 | -3,445 | -7,631 | -31,111 | -38,155 | -155,555 | -404,443 | -2,022,215 |
