Frequently Asked Questions
LCM (Least Common Multiple) is the smallest positive integer divisible by all numbers. HCF (Highest Common Factor) is the largest integer that divides all numbers without a remainder.
Yes, HCF (Highest Common Factor) is also known as GCD (Greatest Common Divisor) or GCF (Greatest Common Factor).
LCM is commonly used to find common denominators when adding or subtracting fractions, and to coordinate events that repeat at different intervals.
