List the primes up to 20 (2, 3, 5, 7, 11, 13, 17, 19) and note that the largest possible prime in the sum is 13 because no two primes add up to and of course 19 is too large as well. Also, observe that 2, the only even prime, must be in the sum, because the sum of three odd primes cannot never be 20. Starting with 2 and 3, we see that is not prime. Next, 2 and 5 give , a prime, so one such increasing sequence is 2, 5, 13. Next, we take 2 and 7, and we see that is prime as well, giving us the second sequence 2, 7, 11. 11 and 13 are already included, so we are done. Thus, there are increasing sequences of three distinct prime numbers that have a sum of 20.
Seven of them.
Two prime numbers such that their sum is 22:- i) 19 and 3 ii) 17 and 5 If we don't consider the prime numbers to be distinct then 11 and 11 is also a solution.
Composite numbers are distinct from prime numbers, but not completely opposite.
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.
A prime number is a number with exactly 2 divisors: 1 and itself. Because of this, the only common divisor of two distinct prime numbers is 1, thus 1 is the gcf. So the correct answer would be: Given two prime numbers, namely x and y, the gcf is --- 1, if x and y are unequally --- x, if x=y.
Prime numbers have one distinct prime factor.
The GCF of any set of distinct prime numbers is 1.

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.
4 of them, 3 distinct.
2 + 3 = 5
Distinct prime factors are 3 and 5.
The GCF is 1.
Seven of them.
It will always be 1.
Three distinct prime factors, eight total.
16 if the prime factors don't have to be distinct. 210 if they do.
