Answer:
(i) LCM Of
12 and 18
Factors of 12 = 2 , 3 , 4 , 6 , 12
Factors of 18 = 2, 3 , 6 , 9 , 18
SAME FACTORS IN BOTH = 2, 3 , 6
LCM = 2x 3 x 6
= 36
(ii) HCF of
12 and 18
Factors of 12 = 2, 3 ,6, 4, 12
Factors of 18 = 2, 3 , 6 , 9 , 18
HCF is highest common factor which here is 6.
So, HCF = 6.
I HOPE ITS HELPFUL.
