Since 1 is a factor of every positive integer, there are no numbers with only even factors.
No, only square numbers have an odd number of factors.
No. For example, 30 is an even number but two of its factors are odd; 5 and 15.
No. the factors may be both even but only one of them needs to be.
Numbers with only two factors, the number itself and one, are called prime numbers. Examples of prime numbers are 2 (which is the only even prime number) and 17.
No. 24 has 3 as a factor. 30 has 15 as a factor.
The only even number that is prime is 2. No other even numbers can be prime because 2 is a factor of them. Prime numbers can have only two factors: 1 and itself.
no. 2 is the only even prime number. Prime numbers are numbers that only have two factors; one and itself. E.g. The number 7 only has two factors- 1x7=7. 2 is a factor of all even numbers, therefore no other even numbers are prime. They are composite. 2, however, is a prime number, as it's only factors are itself (2) and 1.
All even numbers are composite numbers except 2 which is the only even prime number because it has only two factors which are itself and one.
yes because even numbers only go into 2 4 6.....
One number: 2. Its factors are 1 and 2. Any other number either has no even factors or at least two: 2 and itself. Now start paying attention in 4th grade math!
Yes, there is an even number that is a prime number, and it is two (2). It is, however, the only even number that is prime. All other even numbers are divisable by two. A prime number can only be divided by 1 and itself. Two meets this qualification, and is the only even number that does.
