What is the lcm of 2 and 4 and 10?
To find the least common multiple (LCM) of 2, 4, and 10, we need to first find the prime factorization of each number. The prime factorization of 2 is 2, 4 is 2^2, and 10 is 2 * 5. To calculate the LCM, we take the highest power of each prime factor that appears in the factorizations of the numbers, which gives us 2^2 * 5 = 20. Therefore, the LCM of 2, 4, and 10 is 20.
What is the LCM of 4 and 5 and 8 and 10?
To find the Least Common Multiple (LCM) of 4, 5, 8, and 10, we first need to find the prime factorization of each number. The prime factorization of 4 is 2^2, 5 is a prime number, 8 is 2^3, and 10 is 2 * 5. Then, we take the highest power of each prime factor that appears in any of the numbers: 2^3 * 5 = 40. Therefore, the LCM of 4, 5, 8, and 10 is 40.
