Finding the LCM and HCF using Prime Factor Decomposition

Finding the LCM and HCF using Prime Factor Decomposition. We found that: 2 2 x 5 = 20 and 2 5 = 32. The highest common factor is found by using the prime factors that are common in both numbers. 2 x 2 x 5 = 20 2 x 2 x 2 x 2 x 2 = 32. 2. 2. 2. 2. x. = 4.
