About GCD & LCM
GCD (Greatest Common Divisor)
The largest positive integer that divides each of the numbers without a remainder. Also called HCF (Highest Common Factor).
LCM (Least Common Multiple)
The smallest positive integer that is divisible by each of the numbers. Useful for adding fractions with different denominators.
