165 is a composite number because it has factors other than 1 and itself. It is not a Prime number.

The 8 factors of 165 are 1, 3, 5, 11, 15, 33, 55, and 165.

The factor pairs of 165 are 1 x 165, 3 x 55, 5 x 33, and 11 x 15.

The proper factors of 165 are 1, 3, 5, 11, 15, 33, and 55 or,

if the definition you are using excludes 1, they are 3, 5, 11, 15, 33, and 55.

The prime factors of 165 are 3, 5, and 11.

The 3 distinct prime factors (listing each prime factor only once) of 165 are 3, 5, and 11.

The prime factorization of 165 is 3 x 5 x 11.

NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common. And therefore you need 2 or more numbers to have a LCM and GCF
