# NCERT Solutions Class 10 Maths Chapter 1 Exercise 1.2 Real Numbers

NCERT solutions for class 10 maths chapter 1 exercise 1.2 Real Numbers deals with the concept of the Fundamental Theorem of Arithmetic. This theorem states that every composite number can be factorized as a product of primes, and this factorization is unique irrespective of the order of the prime factors. In other words, given any composite number, there is one and only one way to write it as a product of primes, as long as we are not particular about the order in which the primes occur. It has many applications, both in mathematics as well as other fields. NCERT solutions class 10 maths chapter 1 exercise 1.2 consists of 7 questions, of which four are short and three long answer type questions.

With the help of exercise 1.2, students will also explore the concepts of HCF and LCM. Using this theorem we can say that the product of the smallest power of each common prime factor in the numbers gives the HCF. Similarly, the product of the greatest power of each prime factor, involved in the numbers is the LCM. Students will learn the applications of all such concepts.

## NCERT Solutions Class 10 Maths Chapter 1 Exercise 1.2 Tips

NCERT Solutions Class 10 Maths Chapter 1 Exercise 1.2 Real Numbers will help kids explore the concepts of HCF and LCM in depth. Most of the questions in this exercise are fairly straightforward and a student is only required to have exceptional calculation abilities to minimize mistakes as well as improve their accuracy. The first correct proof of the Fundamental theorem was given by Carl Freidrich Gauss.

NCERT Solutions for Class 10 Maths Chapter 1 Exercise 1.2 helps kids understand the application of the Fundamental Theorem of Arithmetic. This can be done by revising some key points such as the prime numbers can be repeated while doing the prime factorization, the order of the numbers does not matter, and the prime factorization of a natural number is always unique, except for the order in which the factors are placed.
