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 2,212,045, 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 | 2,212,045 | |
| -1 | -2,212,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,212,045.
Example:
1 x 2,212,045 = 2,212,045
and
-1 x -2,212,045 = 2,212,045
Notice both answers equal 2,212,045
With that explanation out of the way, let's continue. Next, we take the number 2,212,045 and divide it by 2:
2,212,045 ÷ 2 = 1,106,022.5
If the quotient is a whole number, then 2 and 1,106,022.5 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 | 2,212,045 | |
| -1 | -2,212,045 |
Now, we try dividing 2,212,045 by 3:
2,212,045 ÷ 3 = 737,348.3333
If the quotient is a whole number, then 3 and 737,348.3333 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 | 2,212,045 | |
| -1 | -2,212,045 |
Let's try dividing by 4:
2,212,045 ÷ 4 = 553,011.25
If the quotient is a whole number, then 4 and 553,011.25 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 | 2,212,045 | |
| -1 | 2,212,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 185 | 407 | 1,087 | 2,035 | 5,435 | 11,957 | 40,219 | 59,785 | 201,095 | 442,409 | 2,212,045 |
| -1 | -5 | -11 | -37 | -55 | -185 | -407 | -1,087 | -2,035 | -5,435 | -11,957 | -40,219 | -59,785 | -201,095 | -442,409 | -2,212,045 |
