A composite number has more than two factors whereas a prime number has only two factors
A prime number is a positive integer that has exactly two different factors: 1 and itself. This is why 1 is not a prime number: it has the factors 1 and itself, but they are the same - it does not have exactly two different factors.
a prime number
A prime number is a whole number that has only two distinct factors: 1 and the number itself. A composite number has at least three distinct factors.

Logically, the smallest number with 4 different prime factors would have to be the product of the smallest four prime numbers. So the smallest natural number with four different prime factors is 210 (2*3*5*7).
No, 4 has one prime factor.
16,777,216 is one.

Yes. To be composite, the first number has at least 2 prime factors, the second number also has at least prime factors; the product of the two will have at least 4 prime factors, so it must be a composite number.
If by "least number" you mean "smallest positive integer", then the answer is the product of the three smallest primes: 2x3x5 = 30
A prime number has only two factors, one and the number itself. A composite number has more than two factors. Factors can be either prime or composite.
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. When finding the factors of a number, you find all the factors. The prime factorization is a multiplication string of just prime factors that will total the given number.
the least number is 210 which is divisible by four different prime numbers.
Since there are an infinite number of prime numbers, there are infinite numbers with any given number of prime factors.
2 factors, but a prime number has only two factors (itself and one). Note that 1 is not considered to be a prime number.
