What is the greatest common multiple of 15 and 45 and the least common multiple of 15 and 45?
The Greatest Common Factor of 15, 45: 15The Least Common Multiple of 15, 45: 45
Is 45 a factor 5?
No, but 5 is a factor of 45.
Is 3d-7 and 7-3d an opposite factor?
No, they are the same factor since each is a multiple (-1 times) the other.
What is the least common multiple of 9 45 and 81?
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.
What is the least common multiple of 45 75 and 105?
To find the least common multiple (LCM) of 45, 75, and 105, we first need to prime factorize each number: 45 = 3 x 3 x 5, 75 = 3 x 5 x 5, and 105 = 3 x 5 x 7. Then, we identify the highest power of each prime factor that appears in any of the factorizations: 3^1, 5^2, and 7^1. Finally, we multiply these highest powers together to find the LCM, which is 3 x 5^2 x 7 = 525. Therefore, the least common multiple of 45, 75, and 105 is 525.
