As both 2 and 5 are prime numbers the lowest common multiple is the product of 2 and 5 LCM 2 5 10 They do not have any common factors other than 1 so we need 2 and 5 LCM 2xx5 10 A multiple is a number equal to or greater than a number referred to And Least Common Multiple is 72 Another shorter way is to write numbers as multiplication of its prime factors 8 2 2 2 2 comes three times 12 2 2 3 2 comes twice and 3 once 18 2 3 3 2 comes once and 3 twice So maximum times is three times for 2 and two times for 3 Hence Least Common Multiple is 2 2

First factor each number into its prime factors 15 3 5 20 22 5 Now multiply each different factor based on the highest exponent lcm 22 3 5 60 The least common multiple is 60 Answer link iOS Android 144 8 2 3 12 2 2 3 16 2 4 36 2 2 3 2 So the lowest common multiple must be 2 4 3 2 Or 144 The first thing to notice is that
