Are 2 and 3 twin primes

Answered By: Jacob Williams Date: created: Dec 30 2021

Usually the pair (2, 3) is not considered to be a pair of twin primes.

Since 2 is the only even prime, this pair is the only pair of prime numbers that differ by one; thus twin primes are as closely spaced as possible for any other two primes..

What is the easiest way to find a prime number

Answered By: John Hall Date: created: Apr 29 2022

To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can’t be a prime number. If you don’t get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number (see table below).
