Two numbers that have no common factors greater than one are considered co-prime or relatively prime. Their LCM is their product.
The Greatest Common Factor depends upon the numbers for which there are common factors and it is the greatest one of them; it can be greater than 18, for example the greatest common factor of 40 and 100 is 20. The greatest common factor must be one of the factors of each of the numbers. As the factors of each number cannot be greater than that number, the greatest common factor of a set of numbers cannot be greater than the least number. If this number is not greater than 18 then the greatest common factor of the numbers cannot be greater than 18. Even if the least number is greater than 18 it is possible that the greatest common factor of a set of numbers is still not greater than 18, for example the greatest common factor of 20, 30 and 50 is 10.
The only common factors of 38 and 90 are 1 and 2, so it is not possible for a common factor of 38 and 90 to be greater than 2, much less 20.
25 and 50 are the factors of 50 greater than 10.
If the GCF of a given pair of numbers is 1, the LCM will be equal to their product. If the GCF is greater than 1, the LCM will be less than their product. Or, stated another way, if the two numbers have no common prime factors, their LCM will be their product.
All numbers have common factors greater than zero.
The least common factor for two numbers is always one. The least common multiple for two numbers which have no common factors greater than one is their product.
Two numbers that have no common factors greater than one are considered co-prime or relatively prime. Their LCM is their product.
There are none.
Their product.
They are called co-primes.
...common factors greater than one.
They are all:-- real-- rational-- integers-- greater than 'pi'-- greater than 'e'-- positive (greater than zero)-- less than 12-- factors of 792
Because 14 and 75 don't have any common factors greater than 1.
No. There are no factors of 18 greater than 18.
