Their product.
When the numbers have a common factor (other than 1).
When they have a common prime factor. When their GCF is greater than 1.
If the HCF (Highest Common Factor) of two numbers is 1, then the two numbers are relatively prime and their LCM is the product of the two numbers.
When their GCF is greater than 1. When they have a prime factor in common.
When the GCF is greater than 1. When they have a prime factor in common.
Yes. If one number is a factor of the other, the greater number will be the LCM of the two.
The LCM will never be less than the GCF of a set of numbers.
The LCM of two numbers will never be less than the GCF.
If two numbers have no common factor greater then one, then their LCM is the two numbers multiplied together. Example: 9 and 14 have no common factors. Their LCM is 9 x 14, which is 126.
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
If there is no common factor greater than 1, then the lcm of those numbers is the product of those numbers. eg hcf(5, 7) = 1 → lcm(5, 7) = 5 x 7 = 35 eg hcf(4, 9) = 1 → lcm(4, 9) = 4 x 9 = 36
The LCM of any two consecutive numbers greater than zero is the two numbers multiplied together. eg. the LCM of 10 and 11 is: 10*11=110
