What is the least common multiple of 14 28 and 49?

The least common multiple (LCM) of 14, 28, and 49 can be found by first determining the prime factors of each number. The prime factorization of 14 is 2 x 7, 28 is 2^2 x 7, and 49 is 7^2. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2^2 x 7^2 = 196. Therefore, the least common multiple of 14, 28, and 49 is 196.
