The remaining prime factors of 72 are 2 and 3. Therefore, L.C.M. = Common prime factors of 60 and 72 * the prime factors left in 60 * the prime factors left in 72. = 2 * 2 * 3 * 2 * 3 * 5. = 360. Therefore, L.C.M. of 60 and 72 is 360. Directions: Solve the following problems. Also write at least ten examples of your own.
