See lessH.C.F. of co-prime numbers 4 and 15 was found as follows by factorization: 4 = 2 x 2 and 15 = 3 x 5 since there is no common prime factor, so H.C.F. of 4 and 15 is 0. Is the answer correct? If not, what is the correct H.C.F.?
No. The correct H.C.F. is 1. https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-3/
