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 13,344,779, 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 | 13,344,779 | |
| -1 | -13,344,779 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,344,779.
Example:
1 x 13,344,779 = 13,344,779
and
-1 x -13,344,779 = 13,344,779
Notice both answers equal 13,344,779
With that explanation out of the way, let's continue. Next, we take the number 13,344,779 and divide it by 2:
13,344,779 ÷ 2 = 6,672,389.5
If the quotient is a whole number, then 2 and 6,672,389.5 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 | 13,344,779 | |
| -1 | -13,344,779 |
Now, we try dividing 13,344,779 by 3:
13,344,779 ÷ 3 = 4,448,259.6667
If the quotient is a whole number, then 3 and 4,448,259.6667 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 | 13,344,779 | |
| -1 | -13,344,779 |
Let's try dividing by 4:
13,344,779 ÷ 4 = 3,336,194.75
If the quotient is a whole number, then 4 and 3,336,194.75 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 | 13,344,779 | |
| -1 | 13,344,779 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 127 | 883 | 889 | 2,159 | 6,181 | 15,011 | 15,113 | 105,077 | 112,141 | 784,987 | 1,906,397 | 13,344,779 |
| -1 | -7 | -17 | -119 | -127 | -883 | -889 | -2,159 | -6,181 | -15,011 | -15,113 | -105,077 | -112,141 | -784,987 | -1,906,397 | -13,344,779 |
