What does LCM stand for?

• A. Low Cost Move
• B. Limited Cost Move
• C. Local Coordinated Move
• D. Long-term Cost Move

Answer: (A)

LCM stands for Least Common Multiple—the smallest number that is a multiple of two or more integers. This concept helps you find when two repeating events line up or when fractions with different denominators can be rewritten with a common denominator.

To find it, factor each number and take the highest power of every prime that appears. For example, for 4 and 6: 4 = 2^2, 6 = 2 × 3. Use 2^2 and 3, giving 2^2 × 3 = 12. So 12 is the earliest number that both 4 and 6 divide into. You can also list multiples to see the first common one: 4, 8, 12… and 6, 12… first shared is 12.

The phrases like “Low Cost Move,” “Limited Cost Move,” “Local Coordinated Move,” or “Long-term Cost Move” aren’t used to define LCM in mathematics; LCM refers specifically to the smallest common multiple.
