The LCM of the given numbers is the product of all different prime factors to their greatest power. If there are no exponents, the greatest power of the prime factors is 1 and each different prime factor is used in the multiplication:prime factors of 15 are 3 x 5;prime factors of 21 are 3 x 7;the LCM of 15 and 21 is 3 x 5 x 7 = 105
