Taking each number in turn we factor it into primes :- 1) 48 = 2 * 2 * 2 * 2 * 3 = 2 ^4 * 3 ^1 2) 70 = 2 * 5 * 7 = 2 ^1 * 5 ^1 * 7^1 For each prime factor we take the one with the largest number as the index, eg for the factor 2 , we have 4 and 1. The largest is 4 and so on for each prime factor that occurs and then multiply them together so we have all together 2 ^4 * 3 ^1 * 5^1 * 7^1 = 16*3*5*7 = 1680 which is the Lowest Common Multiple of 48 and 70.
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 48 and 70 is 1680.
