Who Made the Error? A teacher gave her class an assignment to create a math puzzle that would challenge the class.
One student was asked to present their problem. The student wrote a large multi-digit number
on the board and asked the other students to tell about the divisors of the number one by one.
The 1student said, "The number is divisible by 2."
The 2nd student said, "The number is divisible by 3."
The 3rd student said, "The number is divisible by 4." (and so on)
The 30th student said, "The number is divisible by 31."
The teacher then commented that exactly two other students who spoke consectutively, gave
incorrect statements. Which two students made incorrect statements? Justify your answer,
