**Euclid’s Division Lemma**

This section also teaches you about Euclid’s Division Lemma. It states that the given two integers a and b, there always exists a unique pair of integers which are named as q and r such that a=b×q+r and 0≤r<b.

**Euclid’s Division Algorithm**

This part of Class 10 Maths Real Numbers teaches you about Euclid’s algorithm theorem. It tells you how Euclid’s Division Algorithm is based on Euclid’s Division Lemma.

Here you will also come to know how to find the HCF of the two given numbers with Euclid’s Division Algorithm say p and g, where p>g. Now, if we are applying Euclid’s theorem to this, then p=g×q+r and 0≤r<g.

Suppose, if we consider r=0, with the HCF as g, now, if we apply Euclid’s division Lemma to g(the divisor) and r (the remainder). With this, we get another pair of remainder and quotient. This method is repeated until a remainder 1 is attained. The divisor that step is the HCF of the given set of numbers.

**The Fundamental Theorem of Arithmetic**

This section of RD Sharma Solutions for Class 10 Maths Chapter 1-Real Numbers, introduces you to prime factorisation and how it is the method of representing a natural number through the multiplication of prime numbers. For example, 36=2 x 2 x3 x 3 is the prime factorisation of 36.

It also explains the Fundamental Theorem of Arithmetic which states that the prime factorisation of the given number should be unique if the arrangement of prime factors is ignored.

For Example 36= 2 x 2 x 3 x 3 or 36 = 2 x 3 x 2 x 3.

In this section, you’ll also learn the method of finding LCM, method of finding HCF, the product of two numbers which is HCF X LCM of the two numbers and application of HCF and LCM in real-world problems.

**Revisiting Irrational Numbers**

This element of Class 10 Maths Real Numbers, explains about the irrational numbers. Basically, these are the numbers which cannot be expressed in the form of a fraction (p/q). Examples of Irrational numbers are √2,π, and e.

You’ll also learn about the number theory, proof of contradiction.

**Revisiting Rational Numbers and Their Decimal Expansions**

This element of RD Sharma Solutions for Class 10 Maths Chapter 1-Real Numbers, teaches you about the terminating and non-terminating decimals.

- When a number stops at a certain point, then it is called terminating decimal.

Example: 8.42, 7.58. 1.23, and so on. - When a decimal number doesn’t terminate after a certain point, then it is considered as non-terminating decimals.
