Prime numbers are integers greater than 1 with no divisors other than 1 and itself; simply list the first five and sum them: 2, 3, 5, 7, 11.
We need to identify and sum the first five prime numbers.
S=тИСi=1nтАЛpiтАЛ
Prime numbers are integers greater than 1 with no divisors other than 1 and itself; simply list the first five and sum them: 2, 3, 5, 7, 11.
Many students incorrectly include 1 as a prime number. 1 is neither prime nor composite, so the sequence must start from 2.
Identify the first five prime numbers
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The first five prime numbers are 2, 3, 5, 7, and 11.
P={2,3,5,7,11}
Calculate the sum
Add these numbers together to find the required sum.
2+3+5+7+11=28
B is correct because the sum of the first five prime numbers (2, 3, 5, 7, 11) is 28.
Prime number identification is essential for LCM, HCF, and factorization problems in competitive exams.
