The prime numbers between 20 and 40 are: 23, 29, 31, 37, 41, 43 and 47.
23+29+31+37+41+43+47 = 251
Prime number next to any prime number is called consecutive prime number. Eg:- 2,3,5,7 are prime numbers

In the prime factorisation of the number, each factor must appear an even number of times.In the prime factorisation of the number, each factor must appear an even number of times.In the prime factorisation of the number, each factor must appear an even number of times.In the prime factorisation of the number, each factor must appear an even number of times.
There is no simple way since there is no known pattern for the exact distribution of primes. You just have to go and check each number to see whether or not it is a prime.
To find prime numbers between 65 and 75, you would first list out the numbers in that range: 66, 67, 68, 69, 70, 71, 72, 73, 74, 75. Next, you would test each number to see if it is divisible by any number other than 1 and itself. Prime numbers have only two factors: 1 and the number itself. By applying this divisibility test to each number in the range, you would identify the prime numbers between 65 and 75, which in this case are 67 and 71.

You can check each individual number, whether it is a prime number. For numbers below 100, it is enough to check whether they are divisible by 2, by 3, by 5, and by 7. If a number is divisible by none of these, it is a prime number.

Each number only has one prime factorization.
Each composite number has its own unique prime factorization.

Neither nine nor sixteen are prime numbers. They are relatively prime to each other.
Every composite number ... that is, one that is not a prime ... can be written as the product of two or more prime numbers. The primes themselves are the exceptions. A prime number is the product of only ' 1 ' and itself, and ' 1 ' is not considered a prime number.
Perhaps because they are next to each other, like 17 and 19, or 11 and 13. A prime number is always an odd number, so not counting the even number between them they are adjacent.
You factor the number into prime factors, dividing each prime out.
