What is the LCM of 38 20 and 28?

Factor out each number into primes to get: 38 = 2 * 19 20 = 2² * 5 28 = 2² * 7 Count the maximum number of distinct primes for all of these values. For instance, if 20 and 28 both have the maximum number of "2" 2, then write out 2². If one number has a prime factor while the rest of the number doesn't, then write out that prime factor. Following these steps, we have this product: 2² * 5 * 19 * 7 = 4 * 5 * 7 * 19 = 2660 So that is the LCM of the given numbers.
