What is the least common multiple of 9 21 and 7?
To find the least common multiple (LCM) of 9, 21, and 7, we first need to find the prime factorization of each number. The prime factorization of 9 is 3^2, 21 is 3*7, and 7 is a prime number itself. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 3^2 * 7 = 63. Therefore, the least common multiple of 9, 21, and 7 is 63.
What is the LCM of 12 9 and 15?
To find the Least Common Multiple (LCM) of 12, 9, and 15, we first need to find the prime factorization of each number. The prime factorization of 12 is 2^2 * 3, the prime factorization of 9 is 3^2, and the prime factorization of 15 is 3 * 5. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2^2 * 3^2 * 5 = 180. Therefore, the LCM of 12, 9, and 15 is 180.
What is the LCM of 3 5 9 and 13?
To find the Least Common Multiple (LCM) of 3, 5, 9, and 13, you first need to find the prime factorization of each number. The prime factorization of 3 is 3, 5 is 5, 9 is 3^2, and 13 is itself. Then, you take the highest power of each prime that appears in the factorizations, which gives you 3^2 * 5 * 13 = 585. Therefore, the LCM of 3, 5, 9, and 13 is 585.
