Hcf and lcm of 30,42 and Verify the products of the numbers

Answer»

Answer:

HCF = 6 , LCM = 210.

Step-by-step explanation:

prime factors of 42=2*3*7

prime factors of 30 = 2*3*5

HCF = 2*3

        = 6.

LCM = 2*3*5*7

        = 210

HCF * LCM = PRODUCT of 2 numbers

LHS = 6*210 = 1260

RHS = 30*42=1260

Therefore, LHS = RHS

Hence Verified.
