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 1,222,147, 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 | 1,222,147 | |
| -1 | -1,222,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,222,147.
Example:
1 x 1,222,147 = 1,222,147
and
-1 x -1,222,147 = 1,222,147
Notice both answers equal 1,222,147
With that explanation out of the way, let's continue. Next, we take the number 1,222,147 and divide it by 2:
1,222,147 ÷ 2 = 611,073.5
If the quotient is a whole number, then 2 and 611,073.5 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 | 1,222,147 | |
| -1 | -1,222,147 |
Now, we try dividing 1,222,147 by 3:
1,222,147 ÷ 3 = 407,382.3333
If the quotient is a whole number, then 3 and 407,382.3333 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 | 1,222,147 | |
| -1 | -1,222,147 |
Let's try dividing by 4:
1,222,147 ÷ 4 = 305,536.75
If the quotient is a whole number, then 4 and 305,536.75 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 | 1,222,147 | |
| -1 | 1,222,147 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 37 | 67 | 493 | 629 | 1,073 | 1,139 | 1,943 | 2,479 | 18,241 | 33,031 | 42,143 | 71,891 | 1,222,147 |
| -1 | -17 | -29 | -37 | -67 | -493 | -629 | -1,073 | -1,139 | -1,943 | -2,479 | -18,241 | -33,031 | -42,143 | -71,891 | -1,222,147 |
