Numbers that have no common factor like 8 and 9 as 8=23 and 9=32 The two of them are not prime but they have no common factor

The prime numbers (factors) of 75 are: 3 and 5

5,1

Prime numbers are: 2 3 5 7 Composite numbers are: 4 6 8 9 10 So the ratio is: 4 to 5

9 times 9=2*8+51 the factor is 3

prime. * * * * * WRONG! They are coprime, not prime. GCF(8, 9) is 1 but neither 8 nor 9 is a prime.

When the two numbers are coprime. Coprime numbers need not be prime numbers - they must not have any factor in common (other than 1). So, for eaxmple, neither 8 nor 9 are prime numbers but they are coprime and so, LCM(8 , 9) = 72

2, 3, 5 are prime numbers but 9 is not a prime number

There are eight prime numbers under 20.
