Relation Between LCM and HCF

Remember

• Product of two numbers =LCM×HCF
• LCM=product of two numbers÷HCF
• HCF =product of two numbers÷LCM
• (HCF×LCM)÷one of the numbers=The other numbers
• The HCF is never greater than the LCM .
• The LCM is never less than any of the two numbers.
• The HCF of two coprime number is 1.
• The LCM of two coprime numbers is their product.
