Prime numbers only have one and themselves as factors.
u remember
There is no simple way. The difficulty wit prime numbers is that there is no pattern.
The math teacher taught the students about prime numbers.
Prime numbers are divisible by only two numbers.
No, there are only 25 prime numbers less than 100.........remember that 1 is classed as unity and is not a prime number and 2 is the only even prime number.
Remember that the number has no other factor than one and that number.
No, there are more normal numbers than prime numbers. Since 2, 3, 5, 13, and 19 are some examples of prime numbers, those only seem to be a few. Remember, numbers can stretch as far as someone wants, so 1,000 isn't a prime number, since you can have 250 and 4 to multiply into it, and 250 and 4 aren't prime numbers. Since the number scale can go on forever, there are more real numbers than prime numbers.
2, 3, 5, 7, and 11 are all prime numbers.
A reversible prime is a number such as 37, where reversing the order of the digits gives 73 which is also a prime.
The number 2, which is a prime number. Any larger even number is a multiple of 2, and therefore not a prime number.
Remember 1 is not a prime number because it is only divisible by itself. 2, 3, 5, 7, 11, 13, 17, 19 These are the prime numbers between 0 and 20. In short, there are 9 prime numbers between 0 and 20.
