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