The L.C.M. of x² − y², x³ − y³ and x³ − x²y − xy² + y³ is

If x and y are co-primes, then their LCM is:

If a ⊕ b = L.C.M. of a and b, and a ⊗ b = G.C.D. of a and b, then (12 ⊗ 16) ⊕ (24 ⊗ 36) will be

Three number are in the ratio of 3 : 4 : 5 and their L.C.M. is 2400. Their H.C.F. is:

Two numbers are in the ratio of 3 : 5. Their L.C.M. is 90. The numbers are

Find the LCM of 4/3, 8/9 and 3/5.
