Squares of prime numbers, among others.
Prime numbers have one factor pair. Composite numbers have two or more pairs. (6,8) and (4,12) are two different factor pairs for 48.
D
The prime factors of 24 are 2 and 3
The greatest common factor of the numbers 2, 46 and 4 is 2.
There are many pairs of numbers whose greatest common factor is 1. 2, 33 5, 81 13, 27 83, 89 8, 571
Since 1, known as the "multiplicative identity", cannot be counted as a factor, there are many pairs of numbers that do not have common factors, such as 2 and 3, 2 and 5, and 3 and 5. There are many pairs of composite (not prime) numbers without common factors, such as 4 and 9. Also, since prime numbers do not have factors, any pair of primes cannot have a common factor, though a pair in which one number is prime may, e.g. 5 and 10.
The largest common factor of two or more numbers is the factor that goes into both numbers. Such as: the largest common factor of 2 and 4 is 2 The largest common factor of two or more numbers is the factor that goes into both numbers. Such as: the largest common factor of 2 and 4 is 2 That's the greatest common factor, or GCF.

Here are pairs of numbers with 6 as their greatest common factor: 6, 18 12, 30 120, 126 306, 318 6 and 12
2
The least common factor of any set of numbers is 1, so your problem won't work. 3, 5 and 10,15 have an LCM of 15. 15, 30 and 45,60 have a GCF of 15.
Because a pair of numbers is a pair of numbers.
It is, because 2 is a common factor for all even numbers.
Prime numbers have one factor pair. Composite numbers have two or more pairs. (6,8) and (4,12) are two different factor pairs for 48.
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.
Factors are numbers you can multiply together to get another number. The factor pairs are: (1, 52) (2, 26) (4, 13)
