Important Topics Covered under Hall and Knight Higher Algebra Solutions Chapter 30: Theory of Numbers
- The word ‘number’ in all the instances in the discussion of this chapter is used to describe a positive integer.
- Prime numbers are the numbers which are not divisible by any other number other than 1 and the number itself. The numbers that are divisible by numbers other than 1 and itself are termed as composite numbers.
- Let us consider a number ‘a’ which divides the product of b and c, that is, bc. If ‘a’ is not a factor of b, then ‘a’ will be certainly the factor of c.
- Let us consider a number ‘a’ which divides the product b.c.d, then the prime number ‘a’ must divide one of the numbers. In that order, if a divides bn then a is a factor of b.
- If a is prime to b and c, it will also be prime to the product of the two bc. Also, if a is prime to bc, it will imply that a is prime to b and c separately.
- If a is prime to band vice versa, then every positive integral power of a will remain prime to each positive integral power of b.
- If a happens to be prime to b then the fractionsandwill be in their lowest possible terms, where n and m are positive integers.
- There is an unlimited number of prime numbers.
- Only prime numbers can never be represented by a given rational algebraical formula.
- There is only one way that a given number can be resolved into the prime factors.
- The number of ways in which a given composite number, N can be resolved into 2 factors, where N=ap bq cr. If N is not a perfect square then the required number isis a perfect square, then the required number is
- Sum of the divisors of a number: Let the number be N=apbqcrthen the sum is
- The product of ‘r’ consecutive integers is divisible by r!
