Question

21. If HCF (54,81)= 27, then find LCM (54,81)
यदि (54ए 81) का HCF 27 हो तो इनका LCM निकालो।​

Answer 1

Answer:

LCM(54,81)=162

Step-by-step explanation:

given that,

HCF(54,81)=27

we know that .,

hcf(a,b)×lcm(a,b)=a×b

then,

hcf(54,81)×lcm(54.81)=54×81

lcm(54,81)=54×81/HCF(54,81)

LCM(54,81)=4374/27

LCM(54,81)=162
