Question

Let g.c.d (a, b) denote the greatest common divisor of integers ‘a’ and ‘b’. Which of the following is/are correct?

• A. g.c.d $(\angle 23+1,\angle 24+1)$ equals 1
• B. g.c.d $\angle 32+1,\angle 33+1)$ is odd
• C. g.c.d. $(\angle 45+1,\angle 46+1)$ is 7
• D. g.c.d $(\angle 45+1,\angle 46+1)$ is odd number greater than

Answer 1

Answer: (A), (B)

The correct options are
A g.c.d $(\angle 23+1,\angle 24+1)$ equals 1
B g.c.d $\angle 32+1,\angle 33+1)$ is odd

Use g.c.d (a, b) = g.c.d(a, b –a)
