Extra Problems for ‘Number of Zeros’ Question Type Example 1: Find the number of zeros in 2145 x 5234 . Solution:When we see the question it looks like a very difficult question but this type of question involving number of zeros is very simple and can be solved in... by Wordpandit | May 11, 2015 | Number System Concepts |
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...
