L.C.M can be defined as Least Common Multiple of all the numbers. H.C.F can be defined as Highest Common Factor of all the numbers. Important formulae: LCM*HCF=product of the numbers. If any number is factor of other then LCM is bigger one and HCF is the other. In general to find LCM,we need to write all the multiples of given numbers and find common number in the series similarly to find HCF of few given numbers,we need to find all factors of given numbers and identify big such factor common for both the numbers but this is a time taking process so we are here for you with some other trick. First let us know about the traditional methods to find LCM,HCF. In traditional method,to find LCM of 4,15 we have to write multiple series of both the numbers. Identify common number in both. Multiples of 4: 4,8,12,16,20,24,28,32,36,40,45,58,52,56, 60 ,64......... Multiples of 15: 15,30,45, 60 ,75.......... we can say 60 is LCM of 4,15 but this takes more time. I

Prime factorization is a method of representing a number in terms of multiples of prime numbers which is more powerful in identifying co-primes, LCM, HCF, number of its factors. What are prime numbers? These are the numbers which have no factors other than one and itself. Divide and rule was

In this post let us clearly know about the classification of the number system.before classifying numbers let us know about numbers and number systems.  what is a number? =>A number can be defined as a group of digits which have some value. what is a number system? =>The systematic way in which numbers are organized

In Boats and stream based problems,we need to calculate either speed or time to reach some point either upstream or downstream. In water,the direction of the flow is downstream and opposite direction is upstream.

One of the important topics in aptitude solving is work-time-efficiency based problems but we should be able to manage time which is possible by solving more and more problems. Important points to remember: If A can finish work in m minutes and B can finish the same work in n minutes then both

Two or more people doing business with the shared pool of resources and shared return on investment refers to Partnership and the one who invested can be considered as a partner. There are many types of partners: Active partner: The partner who manages the business. Sleeping partner: The partner who just invests and doesn't work.

Aptitude solving also comprises of few problems based on age calculation, they are normal but the sentences used there makes it look as if it is complex. The main parts of Age based problems are  Present age
