The LCM of all these numbers is 72. (LCM of 9, 6, 3 is 18.) (LCM of 18, 8, is 72.)
Factors of 18 are 1, 18, 2, 9, 3, 6. Factors of 72 are 1, 72, 2, 36, 3, 24, 4, 18, 6, 12, 8, 9. So, Common Factors of both are: 1, 2, 3, 6, and 18. 18 is the GCF.
Answer: 2160 Solution: -3 x -2 =6 6 x -3 =-18 -18x-4 =72 72x -5=-360 -360x-6 =2160
To find the Least Common Multiple (LCM) of 6, 8, and 18, you need to first find the prime factorization of each number. The prime factorization of 6 is 2 x 3, the prime factorization of 8 is 2 x 2 x 2, and the prime factorization of 18 is 2 x 3 x 3. Then, you take the highest power of each prime factor that appears in any of the numbers: 2^3 x 3^2 = 72. Therefore, the LCM of 6, 8, and 18 is 72.
The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54 The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72
