117 is not prime number because, it is divisible by- 1,3,9,13,39

[@GyanWithBedanta]

35:40 aitu vul ke krile, ans should be 60. Step 1 - convert the decimals into fractions. i.e 25/10 , 12/10, 20/1, 75/10 Step 2 - convert the fractions into smaller one (25/10 = 5/2) (12/10 = 6/5) (20/1 = 20/1) (75/10= 15/2) Step 3 - Use formula = (LCM of 5,6,20,15)/ (HCF of 2,5,1,10) = (60/1) =60 So , correct answer is option a) 60. (Pin the comment)

[@ishachetry5045]

Yes u r correct but when u don’t convert the fraction into smaller one u will get the LCM 300 .
