Number of Prime Numbers between 1 to 100 is

Q. Number of Prime numbers between 1 to 100 is?

Answer: The prime numbers from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. These account for a total of 25 numbers.

A prime number is any whole number that is bigger than 1 and is divided exclusively by 1 as well as the number itself. Prime numbers are natural numbers that have only two factors: one and number itself, or numbers that are divided either by themselves or by one.

A number that cannot be divided further except the number 1 and the number itself is called a prime number. In order to split a number into equal halves, the number must be factored as a mixture of two separate numbers.

1 is neither a prime nor a composite number because it only has one factor, which is one, while prime numbers are natural numbers with two factors, one and the number itself. Primes are natural numbers bigger than one with only one and the number as its components. If a number is a non-zero whole number, it is a prime number. Except for the number 1 and the integer itself, prime numbers cannot be split by any other number. The method of finding prime numbers is known as factorisation or prime factorization.

The prime numbers between 1 and 100 can be found by following steps-

• Compile a list of numbers ranging from 2 to 100.
• The number two is the first integer on the list and is also a prime number; add 2 or skip numbering by 2s to cross out every second item on the list after 2.
• Keep crossing out the next like 3, 5, etc. The no. that are left behind are the prime numbers between 1 and 100.
