Prime-Composite number : This section explains you about Prime-Composite numbers.Prime numbers: The numbers whose components are 1 and the number chin is dubbed Prime numbers.Example : 2,3,5,7,11,13,…2 is the smallest also prime number and 3 is the smallest odd element number.The element numbers approximately 100 room :2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71,73, 79, 83, 89, 97Composite Number : The number which has at least one variable other 보다 1 and the number itself.Example : 4,6,8,9,12,…Note : 1 is neither prime no one composite.Co-prime Numbers : 2 numbers that perform not have a typical factor various other than 1.The an initial 100 composite numbers are4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33,34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58,60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85,86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100, 102, 104, 105, 106, 108,110, 111, 112, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125,126, 128, 129.Example : 35 and 3935 = 7 x 5 x 139 = 3 x 13 x 1Both 35 and 39 are composite numbers,the only element common between them is 1.∴ 35 and 39 are co-prime numbers.Some more examples are : 1) 2,3 ; 2) 3,4 3) 5,6 4) 8,13, and so on.Twin Primes : two prime number are known as twin primes of there is only one composite number in between them.The twin primes in between 1 come 100 are3-5, 5-7, 11-13, 17-19, 29-31, 41-43, 59-61, 71-73Factors and Multiples• Prime-Composite numbers• Divisibility rules• prime Factorization• H.C.F or G.C.F• L.C.M• application on LCMPrime and composite numbers to Factors and MultiplesNumber SystemHome Page
