Identify prime numbers
Prime numbers are special numbers that can only be divided by 1 and the number itself without leaving a remainder. In other words, they have exactly two factors. So the number 3 is a prime number because it is divisible only by 3 and 1. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, and 19.
Many numbers are not prime, they are composite numbers - numbers that have more than two factors. These numbers can be divided by different numbers, not just 1 and themselves. For example, 4 can be divided by 1, 2, and 4.
In this topic you have to identify which of a group of numbers is a prime number. There is only one prime number in each group. The numbers in the groups range from 2 up to 60.
