Prime Numbers Worksheet for Class 5 Maths

The main difference for Grade 5 students is the number of factors each type of number has. Prime numbers have exactly two factors, whereas composite numbers have more than two.

• Prime Numbers: Have only two factors (1 and the number itself). For example, 7 is prime because its only factors are 1 and 7.
• Composite Numbers: Have more than two factors. For example, 10 is composite because its factors are 1, 2, 5, and 10.

The prime numbers from 1 to 50 are the numbers in this range that are only divisible by 1 and themselves. There are 15 prime numbers in this range.

The complete list of prime numbers from 1 to 50 is: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47.

To find all prime numbers from 1 to 100, you can test each number to see if it has any factors other than 1 and itself. A popular method is the Sieve of Eratosthenes.

1. Start by listing all numbers from 2 to 100.
2. Begin with the first prime number, 2. Circle it and cross out all of its multiples (4, 6, 8, etc.).
3. Move to the next number that is not crossed out, which is 3. Circle it and cross out all of its multiples (6, 9, 12, etc.).
4. Continue this process with the next available numbers (5, 7, etc.).
5. The numbers that are circled at the end are all the prime numbers from 1 to 100.

No, the number 1 is not a prime number. It is classified as a unique number because it does not fit the definition of a prime or composite number.

• A prime number must have exactly two distinct factors (1 and itself).
• The number 1 has only one factor, which is 1.
• Therefore, it cannot be a prime number.

Prime factorization is the method of breaking down a composite number into a product of its prime number factors. For a 5th-grade math level, it's like finding the prime number building blocks of any number.

• Example: The prime factorization of 12 is 2 × 2 × 3. Here, 2 and 3 are the prime factors.
• Purpose: It is a fundamental skill in the study of factors and multiples and helps in understanding number properties.

Yes, our maths worksheet PDFs are created to support effective learning and typically come with a corresponding answer key. Having a worksheet with answers allows students and parents to:

• Check the solutions and verify correctness.
