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 12,051,611, 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 | 12,051,611 | |
| -1 | -12,051,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,051,611.
Example:
1 x 12,051,611 = 12,051,611
and
-1 x -12,051,611 = 12,051,611
Notice both answers equal 12,051,611
With that explanation out of the way, let's continue. Next, we take the number 12,051,611 and divide it by 2:
12,051,611 ÷ 2 = 6,025,805.5
If the quotient is a whole number, then 2 and 6,025,805.5 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 | 12,051,611 | |
| -1 | -12,051,611 |
Now, we try dividing 12,051,611 by 3:
12,051,611 ÷ 3 = 4,017,203.6667
If the quotient is a whole number, then 3 and 4,017,203.6667 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 | 12,051,611 | |
| -1 | -12,051,611 |
Let's try dividing by 4:
12,051,611 ÷ 4 = 3,012,902.75
If the quotient is a whole number, then 4 and 3,012,902.75 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 | 12,051,611 | |
| -1 | 12,051,611 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 71 | 143 | 781 | 923 | 1,187 | 10,153 | 13,057 | 15,431 | 84,277 | 169,741 | 927,047 | 1,095,601 | 12,051,611 |
| -1 | -11 | -13 | -71 | -143 | -781 | -923 | -1,187 | -10,153 | -13,057 | -15,431 | -84,277 | -169,741 | -927,047 | -1,095,601 | -12,051,611 |
