Question

Exercise 3.4
Find the HCF and LCM of the numbers and verify whether their product is equal to the
product of numbers.
(a) 75,120
(b) 40,210​

Answer 1

Answer:

If a and b are two positive integers their HCF=h, and LCM=l then,

a×b=h×l

HCF(32,37)=product of common prime factors=1

LCM=maximum powers of prime factors=32∗37∗1=1184

Verification:

HCF∗LCM=1∗1184=32∗37=1184

Answer 2

Answer:

Step-by-step explanation:

fine the product of all composite number less that 10.now ,express their product so obtained as the product of primes exercise 3.4
