Step-by-step explanation:
The number said to be co-prime if 1 is the only common prime factor in it.
19). 59 = 59×1
97 = 97×1
therefore, 59 and 97 are pair of co-prime.because 1 is the only common prime factor in it
20). 161 = 7×23×1
192 = 2×2×2×2×2×2×3×1
therefore, 161 and 192 are pair of co-prime.because 1 is the only common prime factor in it
21).343 = 3×3×3×1
432 = 2×2×2×2×3×3×3×1
therefore, 343 and 432 are not pair of co-prime.because 1 is not the only common prime factor in it
22).512 = 2×2×2×2×2×2×2×2×2×1
945 = 3×3×3×5×7×1
therefore, 512 and 945 are pair of co-prime.because 1 is the only common prime factor in it
23).385 = 5×7×11×1
621 = 3×3×3×23×1
therefore, 385 and 621 are pair of co-prime.because 1 is the only common prime factor in it
24).847 = 7×11×11×1
1014 = 2×3×13×13×1
therefore, 847 and 1014 are pair of co-prime.because 1 is the only common prime factor in it
