lcm(6, 7, 45) = 630. 6 = 2 x 3 7 = 7 45 = 3^2 x 5 lcm = 2 x 3^2 x 5 x 7 = 630
lcm(11, 9, 6, 7) = 1386. 11 = 11 9 = 3^2 6 = 2 x 3 7 = 7 lcm = 2 x 3^2 x 7 x 11 = 1386
The LCM of 7, 6, 12, and 3 is 84.
To find the least common multiple (LCM) of 3, 4, 5, 6, and 7, we first need to find the prime factorization of each number. The prime factorization of these numbers are: 3 = 3, 4 = 2^2, 5 = 5, 6 = 2 * 3, and 7 = 7. The LCM is then calculated by taking the highest power of each prime factor that appears in any of the numbers. Therefore, the LCM of 3, 4, 5, 6, and 7 is 2^2 * 3 * 5 * 7 = 420.
The LCM is 840.
