All numbers between 80 and 100 except 83, 89, and 97 are composites.

All of those numbers are 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.)

All of them except for 83, 89 and 97 which are prime numbers.

The sum of these composite numbers, including 100, is 3989.The sum of all numbers between 1 and 100 is 5,050. From this we need to subtract the sum of 1 plus all the prime numbers below 100. The sum of the primes is 1,060. Subtracting (1 + 1060) or 1,061 from 5,050 yields 3,989.

48, 49 and 50 are all composite.

They are all the numbers except 79 83 89 and 97 which are prime numbers because they have only two factors.

They will be the numbers with more than two factors because prime numbers have only two factors

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.

No, all composite.
