Every whole number has at least one prime factor.
With the possible exception of ' 1 ', whose only factor is ' 1 ' and
isn't considered a Prime number.
Prime numbers have one distinct prime factor.
It will always be 1.
Not a lot. They're both prime numbers. A factor that is prime is used to make other numbers.
Squares (or cubes or more) of prime numbers have one distinct prime factor, but if you're counting them individually, all composite numbers have at least two prime factors.
That depends on the numbers. The GCF of any two prime numbers is 1.
Yes.
16 if the prime factors don't have to be distinct. 210 if they do.
Some prime factorizations have repeated factors. The prime factorization of 72 is 2 x 2 x 2 x 3 x 3. The distinct prime factors of 72 are 2 and 3.
Distinct prime factors are the prime factors that are distinct (or different) from each other. A list of distinct prime factors is a list of one of each different prime number that is a factor. For example, the prime factors of 8 are 2, 2, and 2. The only distinct prime factor is 2, which occurs multiple times.
2 and 2. Prime factors needn't be distinct. Powers of the primes have only this prime as factor and 4 is a power of 2.
41, 43 and 47 are the prime numbers between 40 and 50. Any nonzero number can be a factor.
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
