( 1388 ) D Two Arithmetic Progressions PROGRAMMING math 2500

B"You are given two arithmetic progressions: a1k xe2 x80 x89+ xe2 x80 x89b1 and a2l xe2 x80 x89+ xe2 x80 x89b2. Find the number of integers x such that L xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89x xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89R and x xe2 x80 x89= xe2 x80 x89a1k' xe2 x80 x89+ xe2 x80 x89b1 xe2 x80 x89= xe2 x80 x89a2l' xe2 x80 x89+ xe2 x80 x89b2, for some integers k', xe2 x80 x89l' xe2 x80 x89 xe2 x89 xa5 xe2 x80 x890. The only line contains six integers a1, xe2 x80 x89b1, xe2 x80 x89a2, xe2 x80 x89b2, xe2 x80 x89L, xe2 x80 x89R (0 xe2 x80 x89< xe2 x80 x89a1, xe2 x80 x89a2 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x892 xc2 xb7109, xe2 x80 x89 xe2 x80 x89- xe2 x80 x892 xc2 xb7109 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89b1, xe2 x80 x89b2, xe2 x80 x89L, xe2 x80 x89R xe2 x80 x89 xe2 x89 xa4 xe2 x80 x892 xc2 xb7109, xe2 x80 x89L xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89R).
