Remember the least common multiple is the least whole number that is a multiple of each of two or more numbers. you need to find the smallest number that is a multiple of both 8 and 12. this is the least common multiple.write the prime factorization for each number.8 = 2 × 2 × 212 = 2 × 2 × 3repeat each prime factor the greatest number of times it appears in any of the prime factorizations above.2 × 2 × 2 × 3 = 24the least common multiple of 8 and 12 is 24. that means that the smallest number of pounds is 24, because 3 metal balls weighing 8 pounds each weigh 24 pounds in total and 2 metal cones weighing 12 pounds each weigh 24 pounds in total.the smallest number of ounces that randy and abdullah could each place on their scale is 24.
