What is the LCM of 18 21 use prime factorizations?
2 x 3 x 3 = 18 3 x 7 = 21 2 x 3 x 3 x 7 = 126, the LCM
What is the LCM of 21 and 18 using prime factorization?
18 = 2 x 3 x 3; 21 = 3 x 7. Common factor is 3 so LCM = 18 x 21/3 = 126
What are the LCM of 2 and 3 and 6?
The LCM of 2, 3 and 6 is 6.
What is the LCM of 6 7 and 18?
To find the Least Common Multiple (LCM) of 6, 7, and 18, we first need to find the prime factorization of each number. The prime factorization of 6 is 2 x 3, the prime factorization of 7 is 7, and the prime factorization of 18 is 2 x 3^2. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers, which gives us 2 x 3^2 x 7 = 126. Therefore, the LCM of 6, 7, and 18 is 126.

What is the LCM of 18 21 use prime factorizations?
2 x 3 x 3 = 18 3 x 7 = 21 2 x 3 x 3 x 7 = 126, the LCM
What is the LCM and the GCF of 18 and 21?
To make this easier, let's first factor 18 and 21 into their prime factors: 18=2*3^2 21=3*7 Now it's very easy to find the LCM and GCF. The LCM is 2*3^2*7=126, and the GCF is 3.
