12 has three factor pairs, six if you count their negative counterparts.
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.

The factor pairs of 26 are the pairs of numbers that, when multiplied together, equal 26. The factor pairs of 26 are (1, 26) and (2, 13). These pairs represent the integer factors of 26.
The prime factors of 2 are: Well, 2 has no prime factors because 2 is a prime number The prime factors of 6 are: 1, 2, 3, & 6
The number 67 is a prime number, which means it has only two distinct positive factors: 1 and 67 itself. Therefore, the factor pairs for 67 are (1, 67).
The factor pairs of 21 are:1, 213, 7Therefore, the number 21 has two pairs of positive integer factors.
The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
These are the factor pairs:1750,1875,2350,5250,7175,10125,1470,2550,35
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.
