Composite numbers are those numbers which have more than two factors. On the other hand, prime numbers are those numbers which have only two factors including one and number itself. For example 4, 6, 8 are first three composite numbers. Their factors are;

factors of 4 = 1, 2, 4

factors of 6 = 1, 2, 3 , 6

factors of 8= 1, 2, 4, 8

A composite number is equal to the product of two or more prime numbers. The composite numbers between 100 and 200 are;

100, 102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118,

119, 120, 121, 122, 123, 124, 125, 126, 128, 129, 130, 132, 133, 134,

135, 136, 138, 140, 142, 143, 144, 145, 146, 147, 148, 150, 152, 153, 154, 155, 156, 158, 159, 160,161, 162, 164, 165, 166, 168, 169, 170, 171, 172, 174, 175, 176, 177, 178, 180, 182, 183, 184, 185, 186, 187, 188, 189, 190, 192, 194, 195, 196, 198, 200.

factors of 4 = 1, 2, 4

factors of 6 = 1, 2, 3 , 6

factors of 8= 1, 2, 4, 8

A composite number is equal to the product of two or more prime numbers. The composite numbers between 100 and 200 are;

100, 102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118,

119, 120, 121, 122, 123, 124, 125, 126, 128, 129, 130, 132, 133, 134,

135, 136, 138, 140, 142, 143, 144, 145, 146, 147, 148, 150, 152, 153, 154, 155, 156, 158, 159, 160,161, 162, 164, 165, 166, 168, 169, 170, 171, 172, 174, 175, 176, 177, 178, 180, 182, 183, 184, 185, 186, 187, 188, 189, 190, 192, 194, 195, 196, 198, 200.
