Exercise · ZW-LEAST-COMMON-MULTIPLE-001 · ★☆☆ Basic
What is the least common multiple of \( 4 \) and \( 6 \)?
Choose one option.
Show answer
- B. \( 12 \)
Explanation
The multiples of 4 are 4, 8, 12, and 12 is the first that is also a multiple of 6. The option 24 is a common multiple but not the least.
Review the concept: Least common multiple
The least common multiple of two integers a and b is the smallest positive integer that is a multiple of both, denoted \( \operatorname{lcm}(a,b) \).
\[\operatorname{lcm}(a,b)=\dfrac{|ab|}{\gcd(a,b)}\]
