Prime factorization is the process of expressing a number as a product of prime numbers. For example, 24 = 2³ × 3. It breaks down the number into its smallest divisible prime components. 75 is not divisible by 21. The ...
Co-prime pairs are: Co-prime numbers are two numbers that share no common factors other than 1. Their greatest common divisor (GCD) is 1. Examples include (8, 15) and (21, 22), which have no shared prime factors. (18, 35): GCD = 1 (15, ...
The two numbers are 25 and 400. Their product 25 × 400 = 10000 satisfies the condition. Both numbers end in digits other than 0, meeting the given requirements. Class 6 NCERT Ganita Prakash Chapter 5 Prime Time class 6 Mathematics Textbook ...
Seven consecutive composite numbers between 1 and 100 are 90, 91, 92, 93, 94, 95, and 96. None of these are prime, as each has divisors other than 1 and themselves. Class 6 Mathematics Ganita Prakash Prime Time Class 6 Mathematics Chapter ...
The jump sizes are the common factors of 28 and 70. These factors are 1, 2, 7, and 14. The greatest common divisor (GCD), 14, ensures the smallest jump size reaching both treasures. class 6 Mathematics Textbook Chapter 5 question answer class ...
The number is 15. It is less than 100, divisible by both 3 and 5, and its digits 1 and 5 satisfy the condition where one digit (5) is 1 more than the other (4). Class 6 Mathematics Chapter 5 Prime ...
(30, 45): Not co-prime (GCD = 15). (57, 85): Co-prime (GCD = 1). (121, 1331): Not co-prime (GCD = 11). (343, 216): Co-prime (GCD = 1). class 6 Mathematics Textbook Chapter 5 question answer class 6 Mathematics Chapter 5 Prime Time solutions
False. While most even numbers are composite, the number 2 is an exception. It is the only even prime number because it has exactly two factors: 1 and 2, distinguishing it from composites. Class 6 NCERT Ganita Prakash Chapter 5 Prime ...
