[Maths Class Notes] on Prime Numbers Up to 100 Pdf for Exam

A prime no. is a natural number greater than 1 that is not a product of two smaller natural numbers multiplied together to get the product. We can see that 3 is a prime because the only way of writing it as a product one multiplies with three or three multiples with one provides the three itself.

Primes are the center of attraction of the number system because of the fundamental theorem of arithmetic which says that every natural number greater than 1. This 1 is either a prime itself or can be factorized as a product of primes that are unique to their orders in Mathematics.

What is the Prime Number and How It is Calculated?

The property of being a prime number is known as primality. There is a very simple way but the slightly slow method to check the primality of a given number commonly known as the trial division method. Faster algorithms include the Miller Rabin primality test which is compared to be fast but has a small chance of error. There’s a method that correctly finds the product. The method known as the AKS primality test produces the correct answer in polynomial time but it is very slow to be practical.

The Unsolved Questions Related to Prime numbers

There are infinite prime numbers as demonstrated by Euclid years before. No known simple formula separates prime numbers from composite numbers at that time. Every even integer which is greater than 2 can be mathematically shown as the sum of two primes and the twin prime conjecture. It is that there are innumerable pairs of primes having just one even number between them as a magical point to be noted. The unsolved questions of prime numbers led to the development of various branches of number theory focusing on analytical or algebraic aspects of numbers.

Applications of Prime Numbers

Prime numbers are widely applicable in abstract algebra. These are also used in objects that behave in a generalized way in a way that prime numbers include prime elements and prime ideals. These are used to make the concepts clear and to be understood in an easy way to many.

If anyone is thinking of proving a number whether the number is a prime number first try dividing it by 2, and see if you get the whole number. If you are able to do this then it can’t happen.

Some Smallest Prime numbers

The number 7 has only two factors 1 and itself. The number 11 has only two factors 1 and itself and so on.

There are some controversies that 1 is a prime number. 

The positive integer has exactly two positive divisors. However, 1 only has one positive divisor i.e. 1 itself, so it is not a prime number, in conformity with the fact that prime numbers are always greater than one. Math is a life skill, the idea is to find numbers in the table that are multiples of a number and therefore good skills in Maths.

Diversity in Mathematical Number System

Another way of telling this is that a prime number is a positive integer that is not the product of two smaller positive integers. There are various primality tests from every simple to the complex which allow you to determine if a given number is prime.

There are many sets of numbers found in mathematics to understand the logic of the magical subject and to enjoy the beauty of this wandering magical subject and to grasp its concepts. Number systems are the base of any calculation and the basic concepts in mathematics mastering which gives a real insight to understand any logical or tough calculations of mathematics at any time.
