The answer is 105 because 3,5, and 7 are all prime factors and when you multiply the numbers together it comes out to be 10

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.
Since there are an infinite number of prime numbers, there are infinite numbers with any given number of prime 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).
The number is 875 and its prime factors are 5; 5; 5 & 7.
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 has exactly two factors, 1 and itself. A composite number has more than two factors.
The factors of 38 are 1, 2, 19, and 38. There are four different factors. The prime factors of 38 are 2 and 19. There are two different prime factors.
A prime number has only two factors which are itself and one but a composite number has more than two factors
