Class 6 Maths - GUJARAT
Prime Time
In the Chapter 'Prime Time' of Class 6 Mathematics under the Gujarat Board (GSEB), students explore the fascinating world of numbers. This chapter builds a strong foundation in number theory by teaching students about factors, multiples, prime numbers, and composite numbers. Learners will discover how numbers relate to one another through divisibility rules and prime factorization. Mastering these concepts is essential for solving fractions, finding LCM and HCF, and scoring high in board exams. It develops logical thinking and makes future mathematical problem-solving much easier and faster for students.

Factors
A factor of a number is an exact divisor of that number, meaning it divides the number completely without leaving any remainder.
Multiples
A multiple of a number is obtained by multiplying that number by any whole number, resulting in an infinite series of values.
Prime Numbers
Numbers greater than 1 that have only two distinct factors: 1 and the number itself, such as 2, 3, 5, 7, and 11.
Composite Numbers
Numbers greater than 1 that have more than two factors, meaning they can be divided by numbers other than 1 and themselves.
Prime Factorization
The process of expressing a composite number as the product of prime numbers, often solved using factor trees or division methods.

Frequently Asked Questions
Is 1 a prime number?
No, 1 is neither a prime nor a composite number because it has only one factor (itself).
What is the difference between a factor and a multiple?
A factor is an exact divisor of a number and is always smaller than or equal to the number. A multiple is obtained by multiplying the number and is always greater than or equal to the number.
How can I easily find prime numbers up to 100?
You can use the ancient method called the Sieve of Eratosthenes, where you cross out all the multiples of prime numbers on a chart from 1 to 100.
