322 over 330 in lowest terms is 161/165
660 over 165 = 4/1 = 4
8/11
33/20
If you are looking for the LCM it is 165.
The GCF is 11.
GCF(65, 143, 165) = 1.
8/11 - 4/15 = 120/165 - 44/165 = 76/165 which cannot be simplified.
Since the numbers 76 and 165 share no common positive integer factor, the proper fraction 76/165 is already expressed in its simplest form.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 143 and 165 is 11.
It is just 1 that is the HCF
