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 1,303,841, 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 | 1,303,841 | |
| -1 | -1,303,841 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,303,841.
Example:
1 x 1,303,841 = 1,303,841
and
-1 x -1,303,841 = 1,303,841
Notice both answers equal 1,303,841
With that explanation out of the way, let's continue. Next, we take the number 1,303,841 and divide it by 2:
1,303,841 ÷ 2 = 651,920.5
If the quotient is a whole number, then 2 and 651,920.5 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 | 1,303,841 | |
| -1 | -1,303,841 |
Now, we try dividing 1,303,841 by 3:
1,303,841 ÷ 3 = 434,613.6667
If the quotient is a whole number, then 3 and 434,613.6667 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 | 1,303,841 | |
| -1 | -1,303,841 |
Let's try dividing by 4:
1,303,841 ÷ 4 = 325,960.25
If the quotient is a whole number, then 4 and 325,960.25 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 | 1,303,841 | |
| -1 | 1,303,841 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 41 | 49 | 59 | 77 | 287 | 413 | 451 | 539 | 649 | 2,009 | 2,419 | 2,891 | 3,157 | 4,543 | 16,933 | 22,099 | 26,609 | 31,801 | 118,531 | 186,263 | 1,303,841 |
| -1 | -7 | -11 | -41 | -49 | -59 | -77 | -287 | -413 | -451 | -539 | -649 | -2,009 | -2,419 | -2,891 | -3,157 | -4,543 | -16,933 | -22,099 | -26,609 | -31,801 | -118,531 | -186,263 | -1,303,841 |
