For example, the LCM of 36 and 15 would be: 36 = (4)(3)(3) 15 = (3)(5) the most reoccurring numbers are highlighted in both prime factorizations these highlighted numbers are multiplied together to get the answer: (4)(3)(3)(5) = 180 These same steps are outlined in further ...
factorizations. 5. Name two numbers, both above 20, that are relatively prime. 6. Explain: any multiple of 5 that is greater than 5 must be composite. 7. What is the definition of composite? 8. Find the smallest composite number which is not divisible by any counting number between 1 ...
Using prime factorizations to Find the Least Common Multiples. When finding the LCM (least common multiple) of 15, 32, and 45. Explain why only some 5s and 3s are taken into account when finding the LCM. Two numbers are co-prime and their LCM is 4940. If one of t...
