There are four natural numbers a, B, C and D. the least common multiple of a and D is 36, and the least common multiple of C and D is 90 a. What is the least common multiple of B, C and D? The least common multiple of a and B is 36,

There are four natural numbers a, B, C and D. the least common multiple of a and D is 36, and the least common multiple of C and D is 90 a. What is the least common multiple of B, C and D? The least common multiple of a and B is 36,

36=2x2x3x3
90=2x3x3x5
a. The least common multiple of B, C, d = 2x2x3x5 = 180
