How is the LCM of 8 and 20 different from their greatest common divisor (GCD)?
Opportunities and realistic risks
No, this is not always the case. For example, the LCM of 8 and 20 is 40, not 160 (8 x 20).
The least common multiple (LCM) is a fundamental concept in mathematics that is often misunderstood. Simply put, the LCM of two numbers is the smallest number that is a multiple of both. To find the LCM of 8 and 20, we need to identify the prime factors of each number. The prime factors of 8 are 2 x 2 x 2, while the prime factors of 20 are 2 x 2 x 5. By combining the highest power of each prime factor, we find that the LCM of 8 and 20 is 2 x 2 x 2 x 5 = 40.
