All those numbers are mutually prime (5 and 7 are prime, full stop), so the least common denominator is 5x7x8x9.
The prime numbers (factors) of 75 are: 3 and 5
5,1
5. And primes must be integers.
Prime numbers are: 2 3 5 7 Composite numbers are: 4 6 8 9 10 So the ratio is: 4 to 5
To find the least common multiple (LCM) of 5, 7, 8, and 9, we first need to prime factorize each number: 5 is prime, 7 is prime, 8 = 2^3, and 9 = 3^2. The LCM is the product of the highest power of each prime factor that appears in the factorization of the numbers. Therefore, the LCM of 5, 7, 8, and 9 is 2^3 * 3^2 * 5 * 7 = 2520.

9 is not prime. 9 = 3 * 38 is not prime. 8 = 2 * 2 * 2

5 is a prime number, but not 9, because you can do 3*3=9
No neither of them are because 3x3=9 so it is not prime. 8 is not either because 2x4=8
No.
composite 9 is prime
no neither are prime
