No, prime numbers are divisible only by themselves and 1. 2005 is also divisible by other numbers such as 5
Forty-nine is not a prime number because it is also divisible by seven. Prime numbers are only divisible by one and themselves.
No in fact there is only one even prime number A number evenly divisible by itself and 1. Example 4 6 8 not prime numbers because they are all divisible by 2
prime number is a number that could only be divided by itself and one. odd numbers are naturally not divisible by 2 but odd numbers can be divisible by other numbers. one example is 15. 15 is divisible by itself and one but also by 3 and 5.
the numbers which are divisible by 49 are infinite and 49 is also a prime number .
Yes, it is true that 2 is the only even prime number. All even numbers are evenly divisible by 2 (that is the definition of an even number). The number 2 is also divisible by 2, however, prime numbers, like all numbers, are evenly divisible by themselves, so that does not disqualify 2 from being a prime number.
Two is the only even number that is prime. A prime number is one divisible only by one and itself. Every even number larger than two is divisible by two; hence, it is not prime. Whilst 2 is also divisible by 2, it is not divisible by any number other than 1 and itself; thus, 2 is the only even number that is also prime.
Numbers divisible by 1 & number itself are called prime numbers. These numbers also have the property to be odd numbers.
No. Even numbers are never prime numbers. A prime number is a number that is only divisible by 1 and itself. Even numbers are always divisible by 2, so they are never prime.And 20 is also divisible by 4 and 5. Its factors are 1, 2, 4, 5, 10, and 20.
400 is a composite number because it is divisible by more than two numbers. Because it ends in a 0, the divisibility rules indicate it is divisible by 2, 5, and 10. (It is also divisible by other numbers.) It is not a prime number because a prime number has exactly two factors, 1 and itself.
Neither 4 nor 10 is prime. A prime number is a number that is evenly divisibly only by 1 and itself, not any other numbers. 4 is also divisible by 2. 10 is also divisible by 2 and 5. Therefore, both 4 and 10 are composite numbers.
No. 215 is divisible by numbers other than 1 and itself. It is divisible by 5 and 43 also.
A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
2 is the only even prime number because all other even numbers are divisible by 2, causing them to have a factor in addition to 1 and the number itself.
15 is not a prime number because it is not only divisible by 1 and itself it is also divisible by 3.
Infinite. All prime numbers are odd with the exception of 2. Prime numbers are only divisible by 1 and themselves. That's the rule. The only prime number that is even is 2 since all other even numbers are divisible by 2 also. Hence all prime numbers are odd with the exception of 2.
No, any whole number ending in a digit divisible by 2 is also divisible by 2 and therefore not a prime number.
All prime numbers are odd numbers. If one were even, it would be divisible by two and would, therefore, not be prime.
http://en.wikipedia.org/wiki/List_of_prime_numbers#The_first_500_prime_numbers Also note, all of these prime numbers, except for the number 2, are odd, not even. Even numbers are divisible by 2 and hence, not prime.
1 is not a prime number many people consider it to be one but to be a prime number it must only be divisible by 1 and itself. 1 is only divisible by one and nothing else. the number 1 is also not a composite. Composite numbers are divisible by 1, itself and another number which one is not. Instead it falls under a category called a unit
Numbers divisible by 6 will have at least one 2 and one 3 as prime factors because 2 x 3 = 6. The same is true for 2, 4 and 8. Numbers divisible by 4 are also divisible by 2. Numbers divisible by 8 are also divisible by 4 and 2.
The definition of a prime number is that it is only divisible by itself and one.33 is also divisible by 3 and 11 therefore it is not prime.
Yes. If a number is evenly divisible by both 3 and 4, it will also be divisible by 6.This is because the prime factor of 3 is  -- in other words, 3 is a prime number -- and the prime factors of 4 are [2, 2].Thus, any number that is divisible by 3 and 4 will have as part of its prime factors the set [2, 2, 3]. (The smallest such number is 12, which is 2 x 2 x 3.) Since the prime factors of 6 are [2, 3] -- and [2, 3] is a subset of [2, 2, 3] -- then any such number must also be divisible by 6.Another way to look at it is to note that all numbers which are divisible by both 3 and 4 are also divisible by 12 (which is 3 x 4). Since 12 is divisible by 6, then all multiples of 12 will also be divisible by 6.
1147 is a composite number. To be a prime number, it would have to be divisible only by itself and 1, however it is also divisible by 31 and 37.
