Jared told Alicia that the least common multiple (LCM) of 12 and 20 is 240 because 12 × 20 = 240. Is Jared correct or not and what would be the LCM of 12 and 20?

Jared told Alicia that the least common multiple (LCM) of 12 and 20 is 240 because 12 × 20 = 240.
A Jared is not correct because 12 × 20 = 220, so the LCM of 12 and 20 is 220.
B Jared is correct; since 12 × 20 = 240, the LCM of 12 and 20 is 240.
C Jared is not correct because 4 × 3 = 12 and 4 × 5 = 20, so the LCM of 12 and 20 is 4.
D Jared is not correct because 12 × 5 = 60 and 20 × 3 = 60, so the LCM of 12 and 20 is 60.

    What is the capital of Egypt? ( Cairo )

    1. Quizzma Team

      The correct answer is D.

      Here’s why: The least common multiple (LCM) is the smallest multiple that two numbers share. To find the LCM of 12 and 20, we can list the multiples of each:

      – Multiples of 12: 12, 24, 36, 48, 60, 72, …

      – Multiples of 20: 20, 40, 60, 80, …

      The smallest common multiple is 60, as it’s the first number that appears in both lists. Therefore, Jared is incorrect in saying the LCM is 240.
