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 12,030,629, 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 | 12,030,629 | |
| -1 | -12,030,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,030,629.
Example:
1 x 12,030,629 = 12,030,629
and
-1 x -12,030,629 = 12,030,629
Notice both answers equal 12,030,629
With that explanation out of the way, let's continue. Next, we take the number 12,030,629 and divide it by 2:
12,030,629 ÷ 2 = 6,015,314.5
If the quotient is a whole number, then 2 and 6,015,314.5 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 | 12,030,629 | |
| -1 | -12,030,629 |
Now, we try dividing 12,030,629 by 3:
12,030,629 ÷ 3 = 4,010,209.6667
If the quotient is a whole number, then 3 and 4,010,209.6667 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 | 12,030,629 | |
| -1 | -12,030,629 |
Let's try dividing by 4:
12,030,629 ÷ 4 = 3,007,657.25
If the quotient is a whole number, then 4 and 3,007,657.25 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 | 12,030,629 | |
| -1 | 12,030,629 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 53 | 247 | 689 | 919 | 1,007 | 11,947 | 13,091 | 17,461 | 48,707 | 226,993 | 633,191 | 925,433 | 12,030,629 |
| -1 | -13 | -19 | -53 | -247 | -689 | -919 | -1,007 | -11,947 | -13,091 | -17,461 | -48,707 | -226,993 | -633,191 | -925,433 | -12,030,629 |
