The LCM of 3, 4, 5, and 8 is 120
factoring 5=1*5 15=3*5 40=5*8 so 3*5*8=120
It is infinity but the LCM is 120
8 and 5 share no common factors aside from 1.
To find the least common multiple (LCM) of 5, 7, 8, and 9, we first need to prime factorize each number: 5 is prime, 7 is prime, 8 = 2^3, and 9 = 3^2. The LCM is the product of the highest power of each prime factor that appears in the factorization of the numbers. Therefore, the LCM of 5, 7, 8, and 9 is 2^3 * 3^2 * 5 * 7 = 2520.
