A number can't have a factor greater than itself, so the GCF of a pair of numbers can't ever be greater than the smaller number. The GCF of 9 and 18 is 9.

In every math problem you can ever do you can use prime numbers. 1+3 Both prime numbers. Most numbers are not prime but prime numbers only become a broblem when you try to factor them like in simple algebra.

No, it's never greater than the lesser number.

The HCF is the largest number that both numbers can be divided by. If the HCF is 1, that would suggest that the two numbers share no prime factors. Thus, any two numbers which are coprime will have an HCF of 1. Consecutive numbers are good examples here - 15 and 16, 27 and 28, 104 and 105, all have an HCF of 1.

OK you list all the factors of each number and what ever number is the greatest and the same in both numbers that is the Greatest Common Factor Glad I could help!!!!!!!!!!!!!!!

Yes. The LCM of 9 and 3 is 9.

No but it can be the same as the biggest number as for example the gcf of 30 and 15 is 30

There is none. The GCF is never larger than both numbers. The GCF is never larger than the smaller number.

No. The LCM of 9 and 4 is 36.

No. The LCM of 4 and 6 is 12.
