Quantitative Aptitude - HCF & LCM - Formula & Concept Tutorial
- HCF ( Highest Common Factor ) X LCM ( Least Common Multiple ) of two number = Product Of Two Number
- HCF( Highest Common Factor ) or GCD or GCM of fraction =
- LCM( Least Common Multiple ) of fraction =
- After getting HCF the remaining no. are co-prime.
- HCF of co-prime number is 1.
- If the sum of two numbers is 100, then 1st No. is x and another no. is 100-x.
- HCF is always a factor of LCM
