Prime Factors, HCF and LCMPrime FactorisationAny natural number greater than 1 can be represented in exactly one way as a product of primes. This theorem is called the Fundamental Theorem of Arithmetic. Here is a good way to find the prime factorization of a small number:
Fortunately there are some simple rules to find out whether the number is divisible by a small prime.
ExampleFind the prime factorization of 462: If p is a prime we will call p^{n} a prime power. ExerciseFactorise the number then check your answer.
