Are 9 and 10 coprime numbers?
9 (factors 1, 3, and 9) and 10 (factors 1, 2, 5, and 10) are coprime numbers. Numbers are coprime (also called relatively prime) if 1 is their only common factor.
When is the LCM of two numbers equal to the product of the two numbers?
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
What is the greatest common factor of 9 and 16?
The GCF of 9 and 16 is 1 because it is the only factor shared by both numbers, and thus is the greatest.The p rime factorization of 9 = 3x3The prime factorization of 16 = 2x2x2x2Nothing is common from the prime factorization of both numbers.Therefore, Greatest Common Factor is 1.The greatest common factor of 9 and 16 is 1.
