Numbers having only 2 factors are prime numbers. Their only factors are 1 and themselves. Prime numbers. The only two factors should be 1 and itself.
A number is prime if its only two factors are one and itself.
Yes, prime numbers have factors. A prime number has only two factors(1 and itself).
Any prime number, a prime number is a number of which the only factors are it and itself.
Prime numbers have only two factors, 1 and themselves, so only prime numbers could have only two factors
Prime factors of numbers are small numbers that the bigger (original) number can divide by. The prime factors have to be prime. This means they only have two factors, itself and one.
They are: 41, 43 and 47 that have only 2 factors because they are all prime numbers
None. Prime numbers only have two factors.
None because prime numbers have only two factors
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.
Numbers can be checked to see if they are primes simply by factoring them. Every prime number has exactly two factors, 1 and the number itself. If there are more or less than 2 factors, the number is not a prime. 1 has only one factor so it is not a prime, and composite numbers have 3 or more factors.
Composite numbers have more than two factors. So, the numbers which have two or less than two factors are not composite numbers. Numbers which have exactly two factors are prime numbers. 1 is an exceptional case because it is neither prime nor composite since it has only one factor which is 1.
