Frequently Asked Questions
What is LCM?
LCM (Least Common Multiple) is the smallest positive number that is divisible by all the given numbers. For example, LCM of 4 and 6 is 12.
What is HCF/GCD?
HCF (Highest Common Factor) or GCD (Greatest Common Divisor) is the largest positive number that divides all the given numbers without a remainder. For example, HCF of 12 and 18 is 6.
What is the relationship between LCM and HCF?
For two numbers a and b: LCM(a,b) × HCF(a,b) = a × b. This relationship helps verify calculations and find one value when the other is known.
