How many points with positive integer coefficients are inside

Customer Question

How many points with positive integer coefficients are inside or on the right triangle with vertices (0,0) , (0,A) , (B,0) for positive integers A and B, without adding together A or B numbers?

Hello, my name is Greg. If nonnegative integer coefficients, the number of such points is (1/2)*(ab + a + b + 2 + gcd(a,b)) If meant positive integer coefficients, the number of such points is (1/2)*(ab - a - b + gcd(a,b))
