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 1,222,655, 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 | 1,222,655 | |
| -1 | -1,222,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,222,655.
Example:
1 x 1,222,655 = 1,222,655
and
-1 x -1,222,655 = 1,222,655
Notice both answers equal 1,222,655
With that explanation out of the way, let's continue. Next, we take the number 1,222,655 and divide it by 2:
1,222,655 ÷ 2 = 611,327.5
If the quotient is a whole number, then 2 and 611,327.5 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 | 1,222,655 | |
| -1 | -1,222,655 |
Now, we try dividing 1,222,655 by 3:
1,222,655 ÷ 3 = 407,551.6667
If the quotient is a whole number, then 3 and 407,551.6667 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 | 1,222,655 | |
| -1 | -1,222,655 |
Let's try dividing by 4:
1,222,655 ÷ 4 = 305,663.75
If the quotient is a whole number, then 4 and 305,663.75 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 | 1,222,655 | |
| -1 | 1,222,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 181 | 193 | 905 | 965 | 1,267 | 1,351 | 6,335 | 6,755 | 34,933 | 174,665 | 244,531 | 1,222,655 |
| -1 | -5 | -7 | -35 | -181 | -193 | -905 | -965 | -1,267 | -1,351 | -6,335 | -6,755 | -34,933 | -174,665 | -244,531 | -1,222,655 |
