2.10: Prime Factorization and the Least Common Multiple (Part 2)
WebSolve by using the GCF formula. Solution: List the factors of each number. Factors of 30 - 1, 2, 3, 5, 6, 10, 15, 30 Factors of 42 - 1, 2, 3, 6, 7, 14, 21, 42 6 is a common factor and the greatest one. Hence, the GCF of 30 and 42 is 6. Answer: GCF of 30 and 42 is 6. Example 2: What is the GCF of 60 and 90? Solve by using the GCF formula. Solution: WebNow that we have the list of prime factors, we need to find any which are common for each number. Looking at the occurences of common prime factors in 8, 12, and 20 we can see that the commonly occuring prime factors are 2 and 2. To calculate the prime factor, we multiply these numbers together: GCF = 2 x 2 = 4. ipo facebook opening price
