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 12,054,749, 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 | 12,054,749 | |
| -1 | -12,054,749 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,054,749.
Example:
1 x 12,054,749 = 12,054,749
and
-1 x -12,054,749 = 12,054,749
Notice both answers equal 12,054,749
With that explanation out of the way, let's continue. Next, we take the number 12,054,749 and divide it by 2:
12,054,749 ÷ 2 = 6,027,374.5
If the quotient is a whole number, then 2 and 6,027,374.5 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 | 12,054,749 | |
| -1 | -12,054,749 |
Now, we try dividing 12,054,749 by 3:
12,054,749 ÷ 3 = 4,018,249.6667
If the quotient is a whole number, then 3 and 4,018,249.6667 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 | 12,054,749 | |
| -1 | -12,054,749 |
Let's try dividing by 4:
12,054,749 ÷ 4 = 3,013,687.25
If the quotient is a whole number, then 4 and 3,013,687.25 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 | 12,054,749 | |
| -1 | 12,054,749 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 43 | 203 | 301 | 1,247 | 1,381 | 8,729 | 9,667 | 40,049 | 59,383 | 280,343 | 415,681 | 1,722,107 | 12,054,749 |
| -1 | -7 | -29 | -43 | -203 | -301 | -1,247 | -1,381 | -8,729 | -9,667 | -40,049 | -59,383 | -280,343 | -415,681 | -1,722,107 | -12,054,749 |
