निम्न में से कौन – सा सह – अभाज्य संख्याओं का युग्म है?

(7, 35) (32, 62) (198, 175) (217, 651)

Detailed Solution & Logic

Correct Answer:

(198, 175)

$ \text{Two numbers are co-prime if } \gcd(a,b) = 1 $

Check each pair:

$ (7, 35): \gcd(7,35) = 7 \Rightarrow \text{Not co-prime} $

$ (32, 62): \gcd(32,62) = 2 \Rightarrow \text{Not co-prime} $

$ (198, 175): \gcd(198,175) = 1 \Rightarrow \text{Co-prime} $

$ (217, 651): \gcd(217,651) = 7 \Rightarrow \text{Not co-prime} $

Answer = 198, 175
