If K1 and K2 are two distinct prime numbers, then what is the product of the highest common factor and the least common multiple of K1 and K2?
Answer & explanation
Correct answer: option 4
HCF of any number of prime numbers = 1
LCM of these numbers = product of these numbers
So , the product of the highest common factor and the least common multiple of K1 and K2 is = 1 × k1 × k2 = k1 × k2
