Look for a table of prime numbers. All the odd numbers that are NOT on this list are composite numbers.
No, all composite.

Search the Internet for a list of prime numbers - the Wikipedia article on prime numbers might list a few. All numbers between 2-100 that are not prime, are composite. (The number is not counted as prime, nor as composite.)
primes are 1,2,3,5,7,11,13,17,19,23,29,31,41,43,47,53,59,61,67,71,73,79,83,89,91. all others are composites.
The GCF of all the composite numbers under 100 is 1. For e.g 4 & 9 are composite numbers & their GCF is 1, so if we take other composite numbers along with 4 & 9 the GCF will be 1.
So we eliminate prime numbers. Note that the number 1 is neither prime nor composite. We have left:4689101214151618202122242526272830323334353638394042444546484950515254555657586062636465666869707274757677788081828485868788909192939495969899100

3665, excluding 25 and 100.
There are 41 composite numbers from 50 to 100. Some of the composite numbers from 50 to 100 are 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, and 70.
All composite numbers have more than 2 factors but prime numbers have only 2 factors
All of them except for 83, 89 and 97 which are prime numbers
