The number 18.
12 and 18 have three factor pairs.
Try to factor this number. Look for small factors first - numbers like 2, 3, 5, 7. That is, try whether your number is divisible by such numbers. Once you find such a factor, divide the number by your factor to get the other factor.
36, for one.
Factors come in pairs. If you know one factor, divide it into the number. The answer will be another factor.
its a factor with two pairs of the same number

These are the 16 factor pairs for the number 1,080:1080,1540,2360,3270,4216,5180,6135,8120,9108,1090,1272,1560,1854,2045,2440,2736,30
The factor pairs are all the factors of the number, just listed in pairs.
The GCF is 3.
A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.
Number of factor pairs = number of rectangles
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.
Find the factor pairs of each number. The greatest factor in common is the GCF. A hint, the definition of a prime number is a number with only two factors: 1 and itself.
The number 18.
