What are the first 5 primes?
Prime numbers are numbers that have only 2 factors: 1 and themselves. For example, the first 5 prime numbers are 2, 3, 5, 7, and 11.
What is the smallest 5 digit prime number?
10000
Write the smallest 5-digit number and express it in the form of its prime factors by tree diagram. Answer: Prime numbers are the numbers with two factors, 1 and the number itself. The smallest five-digit number = 10000.

What’s the prime factorization of 220?
When are two numbers considered to be relatively prime?
Two numbers are relatively prime (coprime) if they have no common factor greater than 1. The greatest common factor of relatively prime numbers is equal to 1 and the least common multiple of them is equal to the product of these numbers.
How many prime numbers are between 1 and 1000?
There are a total of 168 prime numbers between 1 to 1000. They 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, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149]
Which is the nth prime number in this calculator?
Calculator Use. For the first 1000 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).
How to calculate the number of prime factors?
Start by testing each integer to see if and how often it divides 100 and the subsequent quotients evenly. The resulting set of factors will be prime since, for example, when 2 is exhausted all multiples of 2 are also exhausted. List the resulting prime factors as a sequence of multiples, 2 x 2 x 5 x 5 or as factors with exponents, 2 2 x 5 2 .
