Best ResponseYou've already chosen the best response.0256 * 1 = 256  Not divisible by 5 256 * 2 = 512  Not divisible by 5 256 * 3 = 768  Not divisible by 5 256 * 4 = 1024  Not divisible by 5 256 * 5 = 1280  Divisible by 5  1280 / 16 = 80  Divisible by 16 Answer = 1280

Best ResponseYou've already chosen the best response.0that's what i was looking for: To find the least common denominator using this method, factor each of the denominators into primes. Then for each different prime number in all of the factorizations, do the following... 1. Count the number of times each prime number appears in each of the factorizations. 2. For each prime number, take the largest of these counts. 3. Write down that prime number as many times as you counted for it in step #2. 4. The least common denominator is the product of all the prime numbers written down.
