Question

LCM and hdf of 3/4 and 2/5 ​

Answer 1

Answer:

Note 2 and 3 are primes and 4=22=2×2

lcm(a,b)=a×bhcf(a,b)

lcm(a,b,c)=lcm(lcm(a,b),c)

hcf(a,b,c)=hcf(hcf(a,b),c)

hcf≡gcd

lcm(2,4)=4

hcf(2,4)=2

lcm(2,3)=6

hcf(2,3)=1

lcm(3,4)=12

hcf(3,4)=1

hcf(2,3,4)=hcf(hcf(2,4),3)=1

lcm(2,3,4)=lcm(lcm(2,4),3)=12
