The greatest number, which divides 171, and 251 leaving remainders 3 and 6 respectively is
Correct Answer: Description for Correct answer:
HCF of (171-3) and (251-6) to find HCF of 168, 245
\( \Large 168 = 2 \times 2 \times 2 \times 3 \times 7 \)
\( \Large 245 = 5 \times 7 \times 7 \)
HCF of 168 and 245 is 7.
The greatest number which divides 171 and 251 leaving remainders 3 and 6 respectively is 7.
