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 13,448,723, 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 | 13,448,723 | |
| -1 | -13,448,723 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,448,723.
Example:
1 x 13,448,723 = 13,448,723
and
-1 x -13,448,723 = 13,448,723
Notice both answers equal 13,448,723
With that explanation out of the way, let's continue. Next, we take the number 13,448,723 and divide it by 2:
13,448,723 ÷ 2 = 6,724,361.5
If the quotient is a whole number, then 2 and 6,724,361.5 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 | 13,448,723 | |
| -1 | -13,448,723 |
Now, we try dividing 13,448,723 by 3:
13,448,723 ÷ 3 = 4,482,907.6667
If the quotient is a whole number, then 3 and 4,482,907.6667 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 | 13,448,723 | |
| -1 | -13,448,723 |
Let's try dividing by 4:
13,448,723 ÷ 4 = 3,362,180.75
If the quotient is a whole number, then 4 and 3,362,180.75 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 | 13,448,723 | |
| -1 | 13,448,723 |
If you did it right, you will end up with this table:
| 1 | 37 | 43 | 79 | 107 | 1,591 | 2,923 | 3,397 | 3,959 | 4,601 | 8,453 | 125,689 | 170,237 | 312,761 | 363,479 | 13,448,723 |
| -1 | -37 | -43 | -79 | -107 | -1,591 | -2,923 | -3,397 | -3,959 | -4,601 | -8,453 | -125,689 | -170,237 | -312,761 | -363,479 | -13,448,723 |
