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 13,450,423, 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 | 13,450,423 | |
| -1 | -13,450,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,450,423.
Example:
1 x 13,450,423 = 13,450,423
and
-1 x -13,450,423 = 13,450,423
Notice both answers equal 13,450,423
With that explanation out of the way, let's continue. Next, we take the number 13,450,423 and divide it by 2:
13,450,423 ÷ 2 = 6,725,211.5
If the quotient is a whole number, then 2 and 6,725,211.5 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 | 13,450,423 | |
| -1 | -13,450,423 |
Now, we try dividing 13,450,423 by 3:
13,450,423 ÷ 3 = 4,483,474.3333
If the quotient is a whole number, then 3 and 4,483,474.3333 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 | 13,450,423 | |
| -1 | -13,450,423 |
Let's try dividing by 4:
13,450,423 ÷ 4 = 3,362,605.75
If the quotient is a whole number, then 4 and 3,362,605.75 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 | 13,450,423 | |
| -1 | 13,450,423 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 133 | 161 | 437 | 3,059 | 4,397 | 30,779 | 83,543 | 101,131 | 584,801 | 707,917 | 1,921,489 | 13,450,423 |
| -1 | -7 | -19 | -23 | -133 | -161 | -437 | -3,059 | -4,397 | -30,779 | -83,543 | -101,131 | -584,801 | -707,917 | -1,921,489 | -13,450,423 |
