Consider the following code snippet. If num_a is 24 and num_b is 72, then the output will be _____.
num_a = int(input('Enter first positive integer:n'))
num_b = int(input('Enter second positive integer:n'))
while num_a != num_b:
if num_b > num_a:
num_b = num_b - num_a
else:
num_a = num_a - num_b
print('GCD is %d' % num_a)
a
The larch

24
c
12
d
6
