finding the prime factors of a composite number

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.

101

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.

2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,and 97 are all prime numbers. The rest are composite

Look for a table of prime numbers. All the odd numbers that are NOT on this list are composite numbers.

So we eliminate prime numbers. Note that the number 1 is neither prime nor composite. We have left:4689101214151618202122242526272830323334353638394042444546484950515254555657586062636465666869707274757677788081828485868788909192939495969899100

It is: 25*75 = 1875

They are the numbers that have more than two factors whereas prime numbers have only two factors and that 1 is not considered to be a composite or a prime number

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.

prime: numbers that can only divided by 1 and itself (except 1) composite: numbers had others factors except 1 and itself 1 - neither prime or composite
