What is the LCM and GCF of 12 and 15?

Therefore, the LCM is 60. Example 3: Find the GCF of 12 and 15, if their LCM is 60. Therefore, the greatest common factor of 12 and 15 is 3.

How do you find the least common multiple of 12?

Prime factorization of 12 = 2 × 2 × 3. Prime factorization of 30 = 2 × 3 × 5. Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60. Therefore LCM (12,30) = 60.
