Need and the method to do Prime factorization of a number.

Need and Method to do Prime Factorization of a Number

The lesson explain the quick method of prime factorization of a factorial function in detail. The method is specially useful when we need to find the divisibility of a factorial function by any Prime or Composite numbers.
The method doesn't limit us from counting powers of composite numbers as all composite numbers are eventually made up of prime numbers ...

Prime Factorization of Factorial Functions

The lessons detail out the method to find factors of any number. It explains the derivation of number of factors (with help of a few basic examples) and little disciplinary methods as well to avoid mistakes which are major bottlenecks in GMAT Prep.

Counting of Factors of a Number

This lesson is aimed at giving exposure of challenging questions testing the understanding of students about calculation of factors of number. I have considered both PS and DS (good quality) questions to further strengthen the concept of calculation of factors of a number . We have also established facts like perfect squares have odd number of factors using multiple methods

Challenging PS and DS on Number of Factors

Numbers often has cyclic nature and follow a pattern so this lesson, with help of a few actual GMAT like problems, explains how cyclicity is instrumental in answering even the most difficult problems of GMAT. The lesson explains the merits of cyclicity principle which is back-bone of number properties.

Cyclicity Principle (Important)

The video discussed the types of GMAT questions based on remainder calculation. Also the video explains in detail the solution of two challenging remainder theorem problems. I am sure students will benefit from it and will be equipped with all they need to have to answer any question made for GMAT based on remainder calculation.

Remainder theorem

The lesson has shared the most basic understanding of LCM and HCF. The lesson also explains the application of LCM and HCF with help of application based GMAT like questions. So the lesson stands very important.

LCM and HCF - Basic to Advanced for GMAT

The lesson explains an important property of LCM and HCF often used in GMAT questions and explains the application by 4 examples and detailed solution.

Please rate me 5 if you learnt any new thing from video. If you have any specific need on any concept then post in a comment and I will ensure that I post a lesson on your need.
