Question

3. HCF of co-prime numbers 4 and 15 was found as follows by factorisation:
4 = 2 x 2 and 15 = 3x5 since there is no common prime factor, so HCF of 4 and is
is 0. Is the answer correct? If not, what is the correct HCF?​

Answer 1

Answer:

the answer is wrong

Step-by-step explanation:

correct answer :

we have given 4=2×2 and 15 =3×5

since there is no common prime factor,so HCF of 4 and 15 is 0

but this is not correct answer which means HCF of 4 and 15 is not equal to zero,it is equal to 1

given as follow:

factor of 4=2×2×1

factor of 15=3×5×1

clearly we can see that 1 is common

.°. HCF =1
