    HCF of co-prime numbers 4 and 15 was found as follows by factorisation: \[4=2\times 2\] and \[15=3\times 5\] since there is no common prime factor, so HCF of 4 and 5 is 0. Is this answer correct? If not what is the correct HCF?

    Answer:

    Answer is wrong. The right HCF of two co-prime numbers 4 and 15 = 1.
