What is 4 not a prime number?
The number 4 is not prime, since it has three divisors ( 1 , 2 , and 4 ), and 6 is not prime, since it has four divisors ( 1 , 2 , 3 , and 6 ). Definition: A composite number is a whole number with more than two integral divisors. So all whole numbers (except 0 and 1 ) are either prime or composite.
What are the 4 prime numbers between 1 and 10?
Out of the first 10 natural numbers, there are four prime numbers. They are 2,3,5 and 7. These numbers are said to be prime as they do not have any other factors other than 1, and the number itself. 2 and 3 are two consecutive prime numbers.
What is the first four digit prime number?
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.
Which of the following numbers is not prime?
It’s answer will be 91. Because 91 can be divisible by 7,13,91,1. It is quite clear that prime number should be divisible only by itself and by 1.
What are the consecutive prime numbers?
For example, the numbers 5,7 and 11 are consecutive prime numbers, although they are not consecutive numbers.

What are the prime numbers from 1 to 8?
What are the prime numbers? There are 8 prime numbers under 20: 2, 3, 5, 7, 11, 13, 17 and 19. The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.
Is there a limit to the number of prime numbers?
For the first 5000 prime numbers, this calculator indicates the index of the prime number. The nth prime number is denoted as Prime [n], so Prime [1] = 2, Prime [2] = 3, Prime [3] = 5, and so on. The limit on the input number to factor is less than 10,000,000,000,000 (less than 10 trillion or a maximum of 13 digits).
What is the study of 4 prime numbers?
4 Number Theory I: Prime Numbers Number theory is the mathematical study of the natural numbers, the positivewhole numbers such as 2, 17, and 123. Despite their ubiquity and apparent sim-plicity, the natural integers are chock-full of beautiful ideas and open problems.
Are there any numbers with no repeated digits?
22 has repeated digit. 102, 194 and 213 have no repeated digit. 212, 171 and 4004 have repeated digits. Input : 10 12 Output : 2 Explanation : In the given range 10 and 12 have no repeated digit where as 11 has repeated digit.
Is the number 4 a prime or composite number?
For example, 4 is a composite number because it has three positive divisors: 1, 2, and 4. All positive integers greater than 1 are either prime or composite. 1 is the only positive integer that is neither prime nor composite. Prime numbers are critical for the study of number theory.
