The LCM of the numbers 3, 77 and 33 is:
231
Express each number as a product of prime factors: \(3 = 3\), \(77 = 7 \times 11\), \(33 = 3 \times 11\).
The LCM is the product of the highest power of every prime that appears: \(3^{1} \times 7^{1} \times 11^{1}\).
Computing, \(3 \times 7 \times 11 = 21 \times 11 = 231\).
Hence, the LCM of 3, 77 and 33 is 231.
