To find the least common multiple (LCM) of 9, 45, and 81, we first need to factorize each number. The prime factorization of 9 is 3^2, 45 is 3^2 * 5, and 81 is 3^4. The LCM is the product of the highest power of each prime factor that appears in any of the numbers. Therefore, the LCM of 9, 45, and 81 is 3^4 * 5, which equals 405.
The LCM is 405.
405
The greatest common factor of 81 and 45 is 9Factors of 45: 1 3 5 9 15 45Factors of 81: 1 3 9 27 81The GCF of 45 and 81 is 9It is: 9
The LCM of 5 and 9 is 45. The LCM is the product of all numbers divided by their highest common factor. 5 is prime, and 9 = 3 x 3 x 1, so the GCF is 1. Thus, the LCM is 5 x 9 = 45.45
