∙ 2012-11-05 08:26:16The 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.

Not all composite numbers are even, but all even numbers except 2 are composite.
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.
So we eliminate prime numbers. Note that the number 1 is neither prime nor composite. We have left:4689101214151618202122242526272830323334353638394042444546484950515254555657586062636465666869707274757677788081828485868788909192939495969899100
The prime numbers from 100 to 110 are 101, 103, 107, and 109.
Look for a table of prime numbers. All the odd numbers that are NOT on this list are composite numbers.
4, 10, 20, 25, 50, 100 are the composite factors of 100.
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.

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.)
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.
Not all composite numbers are even, but all even numbers except 2 are composite.
All composite numbers have more than 2 factors but prime numbers have only 2 factors
