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 13,273,343, 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 | 13,273,343 | |
| -1 | -13,273,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,273,343.
Example:
1 x 13,273,343 = 13,273,343
and
-1 x -13,273,343 = 13,273,343
Notice both answers equal 13,273,343
With that explanation out of the way, let's continue. Next, we take the number 13,273,343 and divide it by 2:
13,273,343 ÷ 2 = 6,636,671.5
If the quotient is a whole number, then 2 and 6,636,671.5 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 | 13,273,343 | |
| -1 | -13,273,343 |
Now, we try dividing 13,273,343 by 3:
13,273,343 ÷ 3 = 4,424,447.6667
If the quotient is a whole number, then 3 and 4,424,447.6667 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 | 13,273,343 | |
| -1 | -13,273,343 |
Let's try dividing by 4:
13,273,343 ÷ 4 = 3,318,335.75
If the quotient is a whole number, then 4 and 3,318,335.75 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 | 13,273,343 | |
| -1 | 13,273,343 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 79 | 239 | 703 | 1,501 | 2,923 | 4,541 | 8,843 | 18,881 | 55,537 | 168,017 | 358,739 | 698,597 | 13,273,343 |
| -1 | -19 | -37 | -79 | -239 | -703 | -1,501 | -2,923 | -4,541 | -8,843 | -18,881 | -55,537 | -168,017 | -358,739 | -698,597 | -13,273,343 |
