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 2,222,627, 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 | 2,222,627 | |
| -1 | -2,222,627 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,222,627.
Example:
1 x 2,222,627 = 2,222,627
and
-1 x -2,222,627 = 2,222,627
Notice both answers equal 2,222,627
With that explanation out of the way, let's continue. Next, we take the number 2,222,627 and divide it by 2:
2,222,627 ÷ 2 = 1,111,313.5
If the quotient is a whole number, then 2 and 1,111,313.5 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 | 2,222,627 | |
| -1 | -2,222,627 |
Now, we try dividing 2,222,627 by 3:
2,222,627 ÷ 3 = 740,875.6667
If the quotient is a whole number, then 3 and 740,875.6667 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 | 2,222,627 | |
| -1 | -2,222,627 |
Let's try dividing by 4:
2,222,627 ÷ 4 = 555,656.75
If the quotient is a whole number, then 4 and 555,656.75 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 | 2,222,627 | |
| -1 | 2,222,627 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 43 | 127 | 407 | 473 | 1,397 | 1,591 | 4,699 | 5,461 | 17,501 | 51,689 | 60,071 | 202,057 | 2,222,627 |
| -1 | -11 | -37 | -43 | -127 | -407 | -473 | -1,397 | -1,591 | -4,699 | -5,461 | -17,501 | -51,689 | -60,071 | -202,057 | -2,222,627 |
