HCF of co-prime numbers 4 and 15 was found as follows by factorisation: 4 = 2 × 2 and 15 = 3 × 5 since there is no common prime factor, so HCF of 4 and 15 is 0. Is the answer correct? If not, what is the correct HCF?
No. The answer is not correct. The correct answer is 1.
correct answer is 1. Bcz 1 is common in both numbers( 1 is factor of both numbers). so answer is 1 not zero. to find HCF find common factors in numbers.
