One through nine all have single digit factors.
Of the numbers from 1 to 30, only 30 has all three of those numbers as factors.
The only factor common to all those numbers is 1.
Squares of prime numbers are the only numbers with three factors, since there must be only one nontrivial divisor for a number to have three factors. That number must thus be prime.
All prime numbers have only two factors. 2, 3, 5, 7, 11
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.
One through nine all have single digit factors.
Prime numbers only have one and itself as factors.
Numbers that have only 2 factors are prime numbers
Prime numbers have only two factors, 1 and themselves, so only prime numbers could have only two factors
No, only square numbers have an odd number of factors.
Numbers whose factors only include one and themselves are called Prime numbers.
1. As long as there are two prime numbers in a set, the only common factor for the set will be 1.
Squares of prime numbers have only three factors.
they are called numbers with 3 factors
Prime numbers have only two factors.
The answer depends on what the numbers have more of when 3 factors!
