Not at all. For example: gcf(101, 102) = 1 gcf(40, 80) = 40
No. Although the greatest common denominator of a pair of numbers is infinite, the size of the numbers doesn't affect the GCF as much as the difference between them. The GCF of 100 and 102 is 2. The GCf of 33 and 66 is 33.
The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.
Any pair of prime numbers as for example 19 and 23
The GCF is 31.
