a. 8 , b.24 c.12 d.24 and 30
Read Solution (Total 4)
-
- b and d is same.and also these all are divisible by 120 which is the LCM of 3 nos.HCF is divisible by LCM.so there is no option mentioned which will not be their HCF

- 120=2*2*2*3*5
now
8=2*2*2
24=2*2*2*3
12=2*2*3
30=2*3*5
here every nos are belongs within it's LCM so no one is possible
but in d there are two options if we see it from that corner (means if 24 is HCF then 30 must not be the HCF) then ans will be d - 13 years agoHelpfull: Yes(12) No(12)
- None of the options are right.
