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 2,222,885, 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 | 2,222,885 | |
| -1 | -2,222,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,222,885.
Example:
1 x 2,222,885 = 2,222,885
and
-1 x -2,222,885 = 2,222,885
Notice both answers equal 2,222,885
With that explanation out of the way, let's continue. Next, we take the number 2,222,885 and divide it by 2:
2,222,885 ÷ 2 = 1,111,442.5
If the quotient is a whole number, then 2 and 1,111,442.5 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 | 2,222,885 | |
| -1 | -2,222,885 |
Now, we try dividing 2,222,885 by 3:
2,222,885 ÷ 3 = 740,961.6667
If the quotient is a whole number, then 3 and 740,961.6667 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 | 2,222,885 | |
| -1 | -2,222,885 |
Let's try dividing by 4:
2,222,885 ÷ 4 = 555,721.25
If the quotient is a whole number, then 4 and 555,721.25 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 | 2,222,885 | |
| -1 | 2,222,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 49 | 211 | 215 | 245 | 301 | 1,055 | 1,477 | 1,505 | 2,107 | 7,385 | 9,073 | 10,339 | 10,535 | 45,365 | 51,695 | 63,511 | 317,555 | 444,577 | 2,222,885 |
| -1 | -5 | -7 | -35 | -43 | -49 | -211 | -215 | -245 | -301 | -1,055 | -1,477 | -1,505 | -2,107 | -7,385 | -9,073 | -10,339 | -10,535 | -45,365 | -51,695 | -63,511 | -317,555 | -444,577 | -2,222,885 |
