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 1,442,441, 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 | 1,442,441 | |
| -1 | -1,442,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,442,441.
Example:
1 x 1,442,441 = 1,442,441
and
-1 x -1,442,441 = 1,442,441
Notice both answers equal 1,442,441
With that explanation out of the way, let's continue. Next, we take the number 1,442,441 and divide it by 2:
1,442,441 ÷ 2 = 721,220.5
If the quotient is a whole number, then 2 and 721,220.5 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 | 1,442,441 | |
| -1 | -1,442,441 |
Now, we try dividing 1,442,441 by 3:
1,442,441 ÷ 3 = 480,813.6667
If the quotient is a whole number, then 3 and 480,813.6667 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 | 1,442,441 | |
| -1 | -1,442,441 |
Let's try dividing by 4:
1,442,441 ÷ 4 = 360,610.25
If the quotient is a whole number, then 4 and 360,610.25 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 | 1,442,441 | |
| -1 | 1,442,441 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 121 | 131 | 143 | 847 | 917 | 1,001 | 1,441 | 1,573 | 1,703 | 10,087 | 11,011 | 11,921 | 15,851 | 18,733 | 110,957 | 131,131 | 206,063 | 1,442,441 |
| -1 | -7 | -11 | -13 | -77 | -91 | -121 | -131 | -143 | -847 | -917 | -1,001 | -1,441 | -1,573 | -1,703 | -10,087 | -11,011 | -11,921 | -15,851 | -18,733 | -110,957 | -131,131 | -206,063 | -1,442,441 |
