It's 15 because the factors of 120 are... (down below) and the factors of 405 are... (down below) and the only factors that are the same are 1, 3, 5, and 15 so it has to be 15.
120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
405: 1, 3, 5, 15, 27, 81, 135, 405
SAME#: 1, 3, 5, 15

What are the factors and prime factors of 405?
405 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 10 factors of 405 are 1, 3, 5, 9, 15, 27, 45, 81, 135, and 405.The factor pairs of 405 are 1 x 405, 3 x 135, 5 x 81, 9 x 45, and 15 x 27.The proper factors of 405 are 1, 3, 5, 9, 15, 27, 45, 81, and 135 or,if the definition you are using excludes 1, they are 3, 5, 9, 15, 27, 45, 81, and 135.The prime factors of 405 are 3, 3, 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 405 are 3 and 5.The prime factorization of 405 is 3 x 3 x 3 x 3 x 5 or, in index form (in other words, using exponents), 34 x 5.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.5(3^4)
