Answer:
(1) 6.
(2) 28.
Step-by-step explanation:
(1) LCM of 3 and 5 = 15.
The numbers which are multiples of both 3
and 5 = 15×1, 15×2, 15×3, 15×4, 15×5, 15×6
= 15,30,45,60,75,90
Total numbers = 6
So, 6 is the correct answer.
(2) We know that,
Product of two numbers = HCF × LCM
= 14×28/14 = 28.
So, 28 is the correct answer.
