Quiz Question 1 of 5
When calculating the GCD of two numbers using Euclid's method, what is the primary reason this recursive method is considered efficient?
Choose the correct answer below:
-
A
It reduces the size of the problem significantly with each step, ensuring the recursion depth is logarithmic relative to the smaller number.
-
B
It requires fewer comparisons by checking divisibility directly, avoiding unnecessary calculations.
-
C
It converts the problem into a simpler additive form, reducing the larger number by a constant value.
-
D
It terminates quickly because it uses multiplication instead of addition or subtraction.
