Each one of them can be expressed as a sum of two primes.
The GCF of two prime numbers is 1.
16 is not prime.
Any integer greater than one can be co-prime.
2
300 is not prime because it has factors that go into it evenly other than 1 and itself. 300's factors include: 1,2,3,4,5,6,10,12,15,20,25,30,50,60,75,100,150, and 300.
odd is a number you cant halve a prime number is a number that you can double itself and it is odd
11x11
because negative nos ARE MINUS(-)
A prime number is a positive integer evenly divisible only by itself and one.
