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 13,402,543, 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 | 13,402,543 | |
| -1 | -13,402,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,402,543.
Example:
1 x 13,402,543 = 13,402,543
and
-1 x -13,402,543 = 13,402,543
Notice both answers equal 13,402,543
With that explanation out of the way, let's continue. Next, we take the number 13,402,543 and divide it by 2:
13,402,543 ÷ 2 = 6,701,271.5
If the quotient is a whole number, then 2 and 6,701,271.5 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 | 13,402,543 | |
| -1 | -13,402,543 |
Now, we try dividing 13,402,543 by 3:
13,402,543 ÷ 3 = 4,467,514.3333
If the quotient is a whole number, then 3 and 4,467,514.3333 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 | 13,402,543 | |
| -1 | -13,402,543 |
Let's try dividing by 4:
13,402,543 ÷ 4 = 3,350,635.75
If the quotient is a whole number, then 4 and 3,350,635.75 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 | 13,402,543 | |
| -1 | 13,402,543 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 133 | 209 | 1,463 | 9,161 | 64,127 | 100,771 | 174,059 | 705,397 | 1,218,413 | 1,914,649 | 13,402,543 |
| -1 | -7 | -11 | -19 | -77 | -133 | -209 | -1,463 | -9,161 | -64,127 | -100,771 | -174,059 | -705,397 | -1,218,413 | -1,914,649 | -13,402,543 |
