Answer

Therefore, the greatest common divisor of 105 and 231 is \(\gcd(105, 231) = 3 \cdot 7 = \boxed{21}\).

Steps

Step 1 :First, we need to find the prime factorization of both numbers. For 105, we have \(105 = 3^1 \cdot 5^1 \cdot 7^1\). For 231, we have \(231 = 3^1 \cdot 7^1 \cdot 11^1\).

Step 2 :The greatest common divisor is the product of the lowest powers of common prime factors. So, \(\gcd(105, 231) = 3^1 \cdot 7^1\).

Step 3 :Therefore, the greatest common divisor of 105 and 231 is \(\gcd(105, 231) = 3 \cdot 7 = \boxed{21}\).
