  1. Answer:

    14,21 and 98

    By using prime factor method,L.C.M. of 14,21 and 98 are given below

    Prime factor of 14=2×7

    Prime factor of 21=3×7

    Prime factor of 98=2×7×7

    ∴L.C.M.=2×3×7×7

    =294

    By using common division method, L.C.M. of 14,21 and 98 are given below

    2 14 21 98

    3 7 21 49

    7 7 7 49

    7 1 1 7

    1 1 1

    ∴L.C.M.=2×3×7×7

    =294
