Question

Find the least common multiple (LCM) of 6 and 12.

Answer 1

Given the numbers 6 and 12, we are asked to find their common multiple. The steps can be seen below;

The Least Common Multiple (LCM) is also referred to as the Lowest Common Multiple (LCM) and Least Common Divisor (LCD). For two integers a and b, denoted LCM(a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b

We will use the listing multiple method to find the answer:

`\begin{gathered} Multiples\text{ of 6 = 6,12,18,24} \\ Multiples\text{ of 12 = 12, 24, 48} \\ \therefore\text{Multiple of 6 and 12 = 12} \end{gathered}`

Answer: Option B
