MC = BCNN(3,5,6)

To find the BCNN (Bình Chưng Nhỏ Nhất) or LCM (Least Common Multiple) of 3, 5, and 6, we can use the prime factorization method.

Prime factorization of 3: 3
Prime factorization of 5: 5
Prime factorization of 6: 2 * 3

To find the BCNN, we need to take the highest power of each prime factor that appears in any of the numbers.

Highest power of 2: 2
Highest power of 3: 3
Highest power of 5: 5

Therefore, the BCNN of 3, 5, and 6 is:

BCNN(3,5,6) = 2^2 * 3^1 * 5^1 = 60

So, MC = BCNN(3,5,6) = 60.
