WebAug 16, 2024 · Notice however that the statement 2 ∣ 18 is related to the fact that 18 / 2 is a whole number. Definition 11.4.1: Greatest Common Divisor. Given two integers, a and b, not both zero, the greatest common divisor of a and b is the positive integer g = gcd (a, b) such that g ∣ a, g ∣ b, and. c ∣ a and c ∣ b ⇒ c ∣ g. WebJan 25, 2015 · We know that $$ 12 = 2^2\cdot 3^1. $$ Now observe the following expression: $$ ({2}^{0} + {2}^{1} + {2}^{2}) \cdot ({3}^{0} + {3}^{1}). $$ As you can see, each of the terms achieved after expanding is a divisor of $12$. And hence the formula for the number of divisors $= (3)(2) = (2 + 1)(1 + 1) = 6$. You can try this for any number.
