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 12,359,825, 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 | 12,359,825 | |
| -1 | -12,359,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,359,825.
Example:
1 x 12,359,825 = 12,359,825
and
-1 x -12,359,825 = 12,359,825
Notice both answers equal 12,359,825
With that explanation out of the way, let's continue. Next, we take the number 12,359,825 and divide it by 2:
12,359,825 ÷ 2 = 6,179,912.5
If the quotient is a whole number, then 2 and 6,179,912.5 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 | 12,359,825 | |
| -1 | -12,359,825 |
Now, we try dividing 12,359,825 by 3:
12,359,825 ÷ 3 = 4,119,941.6667
If the quotient is a whole number, then 3 and 4,119,941.6667 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 | 12,359,825 | |
| -1 | -12,359,825 |
Let's try dividing by 4:
12,359,825 ÷ 4 = 3,089,956.25
If the quotient is a whole number, then 4 and 3,089,956.25 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 | 12,359,825 | |
| -1 | 12,359,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 67 | 157 | 235 | 335 | 785 | 1,175 | 1,675 | 3,149 | 3,925 | 7,379 | 10,519 | 15,745 | 36,895 | 52,595 | 78,725 | 184,475 | 262,975 | 494,393 | 2,471,965 | 12,359,825 |
| -1 | -5 | -25 | -47 | -67 | -157 | -235 | -335 | -785 | -1,175 | -1,675 | -3,149 | -3,925 | -7,379 | -10,519 | -15,745 | -36,895 | -52,595 | -78,725 | -184,475 | -262,975 | -494,393 | -2,471,965 | -12,359,825 |
