Out of those 100 numbers, 21 of them are prime numbers, so the remaining (100 - 21) = 79 are composite.
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, 100 2 and 5 are prime. 1 is neither. The rest are composite.
So we eliminate prime numbers. Note that the number 1 is neither prime nor composite. We have left:4689101214151618202122242526272830323334353638394042444546484950515254555657586062636465666869707274757677788081828485868788909192939495969899100
The product of two prime numbers will be composite.
It is: 25*75 = 1875

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.)
75 composite numbers are there till 100. 100-25=75. Composite numbers are numbers greater than 1 but not prime numbers.
There are 25 prime numbers and 75 composite numbers from 1 to a 100. A prime number has only two factors whereas a composite number has more than two factors.

Numbers....hehe

No, all composite.
