Question 1&2

down=int(input())    # the lower limit of range
up=int(input())      # the upper limit of range
number1=int(input())  # the first divisor
number2=int(input())  # the second divisor
count=0               # nr of solutions
summ=0                # sum of the solutions
for i in range(down,up+1):
   if i%number1==0 and i%number2!=0:
         count+=1
         summ+=i
print('Number of solutions=',count)
print('Sum of solutions=',summ)
