Question

1. If a and b are two positive co-prime integers such that a = 12b, then HCF (a, b) is

(A) 6
(B) 3
(C) 4
(D) 12​

Answer 1

3 is the answer please mark me branliest

Answer 2

Answer:

b

Step-by-step explanation:

coprimes means having no common factors except 1...and since....a & b are coprimes...

hcf ( a, b ) = 1

now...a = 12b which implies...

hcf ( a, b ) = hcf (12b, b) = b

Note : b is the highest number which divides 12b & b
