Given that a, B and C are prime numbers and a = B + C, what is the minimum value of a × B × C?

Given that a, B and C are prime numbers and a = B + C, what is the minimum value of a × B × C?

According to the analysis, we know that a, B and C are prime numbers, and a = B + C, so a = 5, B = 2, C = 3; then a × B × C = 5 × 2 × 3 = 30; answer: the minimum value of a × B × C is 30
