      Find L.C.M. and H.C.F. of 312 and 27 and verify that LCM x HCF = product of the numbers.

    Answer:

      312 = 3 x 104 = 3 x 4 x 26 = 3 x 2 x 2 x 2 x 13 = 23 x 3 x 13; 27 = 3 x 3 x 3 = 33 L.C.M. = 23 x 33 x 13 = 8 x 27 x 13 ; H.C.F. = 3 L.C.M. x H.C.F. = 8 x 27 x 13 x 3 = 312 x 27 = Product of the numbers.
