Question

numbers that are divisible only by 1 and the number itself like: 2, 5, 7 etc​

Answer: These are called prime numbers.

Step-by-step explanation: Prime numbers are numbers that can only be divided by 1 and itself, fun fact, the only even number that is a prime number is 2. All other even numbers are composite numbers, there are loads of odd composite numbers too, a composite number just means a number that can be divided by 1, itself, and at least one other numbers.
