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 300 and 990 is 30

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 168 and 396 is 12
The GCF is 42.
To find the LCM we need to express the numbers as prime factors. 18 = 2x3^2 44 = 2^2 x 11 Now take the highest prime factor of every prime number that occurs. LMC = 2^2 x 3^2 x 11 = 396
