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 12,373,433, 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 | 12,373,433 | |
| -1 | -12,373,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,373,433.
Example:
1 x 12,373,433 = 12,373,433
and
-1 x -12,373,433 = 12,373,433
Notice both answers equal 12,373,433
With that explanation out of the way, let's continue. Next, we take the number 12,373,433 and divide it by 2:
12,373,433 ÷ 2 = 6,186,716.5
If the quotient is a whole number, then 2 and 6,186,716.5 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 | 12,373,433 | |
| -1 | -12,373,433 |
Now, we try dividing 12,373,433 by 3:
12,373,433 ÷ 3 = 4,124,477.6667
If the quotient is a whole number, then 3 and 4,124,477.6667 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 | 12,373,433 | |
| -1 | -12,373,433 |
Let's try dividing by 4:
12,373,433 ÷ 4 = 3,093,358.25
If the quotient is a whole number, then 4 and 3,093,358.25 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 | 12,373,433 | |
| -1 | 12,373,433 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 53 | 443 | 527 | 901 | 1,643 | 7,531 | 13,733 | 23,479 | 27,931 | 233,461 | 399,143 | 727,849 | 12,373,433 |
| -1 | -17 | -31 | -53 | -443 | -527 | -901 | -1,643 | -7,531 | -13,733 | -23,479 | -27,931 | -233,461 | -399,143 | -727,849 | -12,373,433 |
