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 12,414,773, 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 | 12,414,773 | |
| -1 | -12,414,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,414,773.
Example:
1 x 12,414,773 = 12,414,773
and
-1 x -12,414,773 = 12,414,773
Notice both answers equal 12,414,773
With that explanation out of the way, let's continue. Next, we take the number 12,414,773 and divide it by 2:
12,414,773 ÷ 2 = 6,207,386.5
If the quotient is a whole number, then 2 and 6,207,386.5 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 | 12,414,773 | |
| -1 | -12,414,773 |
Now, we try dividing 12,414,773 by 3:
12,414,773 ÷ 3 = 4,138,257.6667
If the quotient is a whole number, then 3 and 4,138,257.6667 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 | 12,414,773 | |
| -1 | -12,414,773 |
Let's try dividing by 4:
12,414,773 ÷ 4 = 3,103,693.25
If the quotient is a whole number, then 4 and 3,103,693.25 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 | 12,414,773 | |
| -1 | 12,414,773 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 109 | 307 | 371 | 763 | 2,149 | 5,777 | 16,271 | 33,463 | 40,439 | 113,897 | 234,241 | 1,773,539 | 12,414,773 |
| -1 | -7 | -53 | -109 | -307 | -371 | -763 | -2,149 | -5,777 | -16,271 | -33,463 | -40,439 | -113,897 | -234,241 | -1,773,539 | -12,414,773 |
