How do you find the lcm
WebWe can use the prime factorisation method or listing the multiples of given numbers, to find the LCM. Also, even division by prime numbers is a method to find the LCM, unless all the numbers are divided completely. How are HCF and LCM related? The relation between LCM and HCF is given by: LCM (a,b) = axb/HCF (a,b)
