# RD Sharma Solutions for Class 6 Maths Chapter 2: Playing with Numbers

The chapter Playing with Numbers entirely comprises factors and multiples of numbers. Multiplying two whole numbers gives a product. The numbers that are used to multiply are the factors of that product. For example, 4*5=20. Hence, 4 and 5 are factors of the number 20. The factor usually divides a number without leaving any remainder. Multiples are most commonly discussed in the case of numbers. A multiple is a result of multiplying a number with a natural number. Without normal division, it is possible to find whether a number is the factor of a number by calculating the sum of numbers at the odd and even places and finally, if the difference between the two is 0, then the number is a factor. The common factors of two numbers can be found by listing out all the factors of each number and finding the intersection of those numbers. Numbers can also be divided as prime and composite based on the number of factors. A number is categorized as a prime if it has no factor other than 1 and the number itself. Any number which is not prime is a composite number. In other words. a number is composite if it has at least one other factor apart from 1 and the number itself. Further, there are twin primes and co-primes. If a given set of prime numbers have only one composite number between them, they are twin primes, and if 1 is the only common factor of two numbers (prime or composite), they are termed as co-primes. Finally, Chapter 2, Playing with Numbers, also focuses on Prime factorization, which is the method to find the prime factors of any given number. This method is used to find the Highest Common Factor (HCF) and the Lowest Common Multiple (LCM) of a given number.
