(i) 120,90 (ii) 50,60 (iii) 37,49​

Answer 1

Explanation:

Solve the others in the same way

for LCM

highest occuring number is chosen from both for example in 120, 2 occur 3 times and in 90 , 2 occur 1 time so we will take that 2 which occur 3 times and solve chosing other no. in the smae way

for HCF

we only chose that no. which is common in both
