Answer:
the lcm of 15 and 18 is 90 and the gcf is 3
Step-by-step explanation:
multiple factors to get lcm and to get GCF Find the prime factorization of 15
15 = 3 × 5
Find the prime factorization of 18
18 = 2 × 3 × 3
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 3
