What is the smallest perfect square which is divisible by both 12 and 5?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 900.
L.C.M(12, and 5) = 60
The prime factorization of 60 = 22 × 3 × 5
Multiply the LCM by the missing factors to get even exponents to determine the perfect square
⇒ 60 × 3 × 5
⇒ 60 × 15 = 900
Thus, 900 is the perfect square
