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

The 6 factors of 45 are 1, 3, 5, 9, 15, and 45.

The factor pairs of 45 are 1 x 45, 3 x 15, and 5 x 9.

The proper factors of 45 are 1, 3, 5, 9, and 15 or

if the definition you are using excludes 1, they are 3, 5, 9, and 15.

The prime factors of 45 are 3, 3, and 5.

Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.

The 2 distinct prime factors (listing each prime factor only once) of 45 are 3 and 5.

The prime factorization of 45 is 3 x 3 x 5 or, in index form (in other words, using exponents), 32 x 5.

NOTE: There cannot be common factors, a greatest common factor, or a least common multiple of a single number because "common" refers to factors or multiples that two or more numbers have in common.
