Number of zeros at the end of a Problem Type: Number of zeros at the end of p! To solve such type of problems we see only pair of 2 x5 in p! . Because if a number is divisible by 10 then it will have 0 in the end and 10= 2×5 so finding number of zeros is... by Wordpandit | May 6, 2015 | Mathematics Concepts, Number System Concepts |
Type : Highest power of p which divides the q! ,where p is not a prime number The approach for this type is same as that for calculating maximum power of prime in any factorial buthere first we will break p into product of primes. Lets take an example to understand... by Wordpandit | May 6, 2015 | Mathematics Concepts, Number System Concepts |
A factorial is a non-negative number which is equal to the multiplication of numbers that are less than that number and the number itself. It is denoted by (!) Let’s take an example to understand this What will be the value of 5! So in the above definition we... by Wordpandit | May 6, 2015 | Mathematics Concepts, Number System Concepts |
Basic Concept of Cyclicity The concept of cyclicity is used to identify the last digit of the number.Let’s take an example to understand this: Example 1: Find the unit digit of 354. Solution: Now it’s a very big term and not easy to calculate but we canfind the last... by Wordpandit | May 6, 2015 | Mathematics Concepts, Number System Concepts |
Product of Factors Perfect square as a product of two factors In case of perfect square number we have odd number of factors i.e. the number of factors are odd hence in that case required number of ways in which we can write perfect square number as a product of its... by Wordpandit | May 6, 2015 | Mathematics Concepts, Number System Concepts |
