Prime Factor Decomposition

Prime Factor Decomposition. What does this mean?. Prime. Factor. Decomposition. Prime Numbers. A number that divides exactly into another number (no remainder),. Break down into smaller parts. So it is the process of breaking numbers down into the prime factors that make it up.

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.
