### What is the least common multiple of 3 12 and 6?

The LCM of 3, 6, and 12 is 12.The least common denominator is the same as the least common multiple.The least common denominator is the smallest multiple divisible by 3, 6, and 12. Since 12 is divisible by 3, 6, and 12, and the smallest multiple of 12 is 12 x 1 = 12, that is the least common denominator or least common multiple.
