A number system is a collection of various symbols which are called digits.

HCF : The largest number that divides two or more numbers is the highest common factor (HCF) for those numbers. For example, consider the numbers 30 (2 x 3 x 5), 36 (2 x 2 x 3 x 3), 42 (2 x 3 x 7), 45 (3 x 3 x 5). 3 is the largest number that divides each of these numbers, and hence, is the HCF for these numbers.HCF is also known as the Greatest Common Divisor (GCD).

LCM : The least number which is exactly divisible by each of the given numbers is called the least common multiple of those numbers. For example, consider the numbers 3, 31 and 62 (2 x 31). The LCM of these numbers would be 2 x 3 x 31 = 186.
To find the LCM of the given numbers, we express each number as a product of prime numbers. The product's highest power of the prime numbers that appear in the prime factorization of any of the numbers gives us the LCM.

I really enjoyed this class. I liked the in-class demos/examples to help remember the material. I also liked that one exam was dropped. It was a nice reward for working hard throughout the semester. I would recommend Eric as an instructor to those looking to take this course.
