1.	If A= 2n+3 and B=n+7 where n is a natural number than HCF of A and B will Be???
Answer» Taking different values of n, we find that A and B are co-prime.When {tex}n = 1, A = 5, B = 8{/tex}When {tex}n = 2, A = 7, B = 9{/tex}When {tex}n = 3, A = 9, B = 10{/tex} and so on....Therefore, {tex}HCF = 1{/tex}
