Question

find the L.C.M and H.C.F by applying the prime factrisation 126,154,231

Answer 1

Prime factorisation of 126 = 2 × 3 × 3 × 7



Prime factorisation of 154 = 2 × 7 × 11


And,


Prime factorisation of 231 = 7 × 3 × 11



Therefore,

HCF of 126 , 154 and 231 = 3.



And,


LCM of 126 , 154 and 231 = 2 × 3 × 3 × 11 × 7 = 1386.
