There are two: 2 and 5.
5 and 2 are the only prime numbers that end in a 5 or 2. A prime number is by definition only divisible by 1 and itself, and all other whole numbers ending in 5 or 2 are divisible by 5 or 2, respectively. Numbers that are not whole numbers cannot be prime.
Two and five!
The number 2 is the only one.
2 and 5 are the only prime numbers that ends with 2 or 5.
2 and 5
Two is the only prime number that ends in "2"
All numbers larger than 5 which end in 5 are divisible by 5 and so are not prime. All numbers larger than 2 which end in 2 are divisible by 2 and so are not prime.
There are an infinite amount of prime numbers, as numbers never end. Prime numbers are numbers that are only divisible by 1 and itself. For example, 2, 3, 5, 53, and 97 are prime numbers.
Prime numbers can not composite as - Prime number has only 2 factors whereas composite have more than 2
No. If they end in 4, they are even numbers and divisible by 2, and therefore are not prime.
When you add two or more prime numbers you will only end up with a whole number and not a decimal number.
No, 38 is not prime. 2 divides 38, as does 19: 38 = 2 times 19. Hint: numbers that end with 0,2,4,6,or 8 are even. Even numbers are divisible by 2 , so except for 2, even numbers are never prime 2 is the only even prime number.
