Answer 1

Answer:

100,150 and 200

By using prime factor method, L.C.M. of 100,150 and 200 are given below

Prime factor of 100=2×2×5×5

Prime factor of 150=2×3×5×5

Prime factor of 200=2×2×2×5×5

∴L.C.M.=2×2×2×3×5×5

=600

By using common division method, L.C.M. of 100,150 and 200 are given below

2 100 150 200
