Ateacher divides the students into three groups for project each group has the same number of students in the total of number students prime or composite

The total number of students is composite

Step-by-step explanation:

* Lets explain how to solve the problem

- A teacher divides the students into three groups for project

- Each group has the same number of students

- We need to know the total number of students is prime number or

 composite number

∵ The least number of any group is 2 students

∵ There are three groups

∵ The number of students in each group equal

∴ The least number of the students is 6

∵ Any number of students must be multiple of 3 because it will

  divide by 3

∵ Any prime number has only two factors 1 and itself

∵ Any multiple of 3 (except 3) has more than two factors

∵ The class can not be 3 students because when divided to 3

   groups each group will have 1 students and the least number of

   students in a group is 2

∴ The number of the students in the class must be composite
