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
Is 16 and 18 coprime numbers?
No.
What is the greatest common factor of 32 and 9?
What number coprime with 18?
coprime numbers with 18 are : 17 and 19.
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.
What numbers has GCF of 1?
Any set of coprime numbers. For example, {8, 9, 10}.

What can go into 9 and 8 evenly?
Only 1. The numbers are coprime.
What are a pair of numbers with a gfc of nine?
Pick any two numbers, x and y that are coprime. That is, they have no factor in common. Then GCF of 9x and 9y will be 9. Pick any two numbers, x and y that are coprime. That is, they have no factor in common. Then GCF of 9x and 9y will be 9. Pick any two numbers, x and y that are coprime. That is, they have no factor in common. Then GCF of 9x and 9y will be 9. Pick any two numbers, x and y that are coprime. That is, they have no factor in common. Then GCF of 9x and 9y will be 9.
What is the gcf of 9 and 125?
The GCF is 1.
What are the two numbers which have 1 as common factor know as?
Any two numbers whose only common factor is 1 are known as coprime. For example, 9 is coprime to 16.
What is LCD of 9 and 50?
Since the two numbers are coprime, LCD(9, 50) = 9*50 = 450
Are 6 and 8 coprime numbers?
No. If two numbers are coprime, they must have no common factors.
What is the GCF of 10 and 23?
The GCF is 1.
