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 12,061,445, 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 | 12,061,445 | |
| -1 | -12,061,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,061,445.
Example:
1 x 12,061,445 = 12,061,445
and
-1 x -12,061,445 = 12,061,445
Notice both answers equal 12,061,445
With that explanation out of the way, let's continue. Next, we take the number 12,061,445 and divide it by 2:
12,061,445 ÷ 2 = 6,030,722.5
If the quotient is a whole number, then 2 and 6,030,722.5 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 | 12,061,445 | |
| -1 | -12,061,445 |
Now, we try dividing 12,061,445 by 3:
12,061,445 ÷ 3 = 4,020,481.6667
If the quotient is a whole number, then 3 and 4,020,481.6667 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 | 12,061,445 | |
| -1 | -12,061,445 |
Let's try dividing by 4:
12,061,445 ÷ 4 = 3,015,361.25
If the quotient is a whole number, then 4 and 3,015,361.25 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 | 12,061,445 | |
| -1 | 12,061,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 185 | 407 | 2,035 | 5,927 | 29,635 | 65,197 | 219,299 | 325,985 | 1,096,495 | 2,412,289 | 12,061,445 |
| -1 | -5 | -11 | -37 | -55 | -185 | -407 | -2,035 | -5,927 | -29,635 | -65,197 | -219,299 | -325,985 | -1,096,495 | -2,412,289 | -12,061,445 |
