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 1,353,443, 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 | 1,353,443 | |
| -1 | -1,353,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,353,443.
Example:
1 x 1,353,443 = 1,353,443
and
-1 x -1,353,443 = 1,353,443
Notice both answers equal 1,353,443
With that explanation out of the way, let's continue. Next, we take the number 1,353,443 and divide it by 2:
1,353,443 ÷ 2 = 676,721.5
If the quotient is a whole number, then 2 and 676,721.5 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 | 1,353,443 | |
| -1 | -1,353,443 |
Now, we try dividing 1,353,443 by 3:
1,353,443 ÷ 3 = 451,147.6667
If the quotient is a whole number, then 3 and 451,147.6667 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 | 1,353,443 | |
| -1 | -1,353,443 |
Let's try dividing by 4:
1,353,443 ÷ 4 = 338,360.75
If the quotient is a whole number, then 4 and 338,360.75 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 | 1,353,443 | |
| -1 | 1,353,443 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 107 | 139 | 749 | 973 | 1,391 | 1,807 | 9,737 | 12,649 | 14,873 | 104,111 | 193,349 | 1,353,443 |
| -1 | -7 | -13 | -91 | -107 | -139 | -749 | -973 | -1,391 | -1,807 | -9,737 | -12,649 | -14,873 | -104,111 | -193,349 | -1,353,443 |
