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 12,076,205, 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 | 12,076,205 | |
| -1 | -12,076,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,076,205.
Example:
1 x 12,076,205 = 12,076,205
and
-1 x -12,076,205 = 12,076,205
Notice both answers equal 12,076,205
With that explanation out of the way, let's continue. Next, we take the number 12,076,205 and divide it by 2:
12,076,205 ÷ 2 = 6,038,102.5
If the quotient is a whole number, then 2 and 6,038,102.5 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 | 12,076,205 | |
| -1 | -12,076,205 |
Now, we try dividing 12,076,205 by 3:
12,076,205 ÷ 3 = 4,025,401.6667
If the quotient is a whole number, then 3 and 4,025,401.6667 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 | 12,076,205 | |
| -1 | -12,076,205 |
Let's try dividing by 4:
12,076,205 ÷ 4 = 3,019,051.25
If the quotient is a whole number, then 4 and 3,019,051.25 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 | 12,076,205 | |
| -1 | 12,076,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 31 | 85 | 155 | 527 | 2,635 | 4,583 | 22,915 | 77,911 | 142,073 | 389,555 | 710,365 | 2,415,241 | 12,076,205 |
| -1 | -5 | -17 | -31 | -85 | -155 | -527 | -2,635 | -4,583 | -22,915 | -77,911 | -142,073 | -389,555 | -710,365 | -2,415,241 | -12,076,205 |
