What I can really explain is how to find them. HCF is the Highest commonfactor, or what is the highest number that can be multiplied with another number to get 140 and 5880. It applies to BOTH numbers.
Lowest common multiple is the lowest number that when you count each number, both numbers reach the same point.
For example, the lowest common multiple between 2 and 3 is 6 because it is the lowest number where they meet.
