H.C.F. of co-prime numbers 4 and 15 was found as follows: `4=2\ *\ 2\ a n d\ 15=3\ *\ 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.?

HCF of co-prime numbers 4 and 15 is

H.C.F. of co-prime numbers 4 and 15 was found as follows:factorisation : 4=2xx 2 and 15= 3 xx 5 .since there is no common prime factor,so H.C.F. of 4 anb 15 is 0.Is the answer correct?If not,what is the correct H.C.F ?

H.C.F.of co-prime numbers 4 and 15 was found as follows: 4=2x2 and 15=3x5 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.?

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

1) what is the HCF of 2 consecutive numbers (i) numbers (ii)even nos (iii)odd nos 2) HCF of co-prime numbers 4 and 15 was found as follows by factorisation: and 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?

The H.C.F. of 12, 15 and 30 is

4=2xx2, 15=3xx5 so H.C.F of 4 and 15 is
