About Prime Factorisation

Prime factorisation is the process of finding the prime numbers that multiply together to give the original number. Every positive integer greater than 1 can be expressed as a unique product of prime numbers.

Why Prime Factorisation is Important:
  • Fundamental Theorem of Arithmetic: Every integer greater than 1 is either a prime number or can be represented as a unique product of prime numbers.
  • Finding GCD and LCM: Prime factorizations make it easy to calculate the greatest common divisor and least common multiple of numbers.
  • Number Theory: Prime factorisation is essential in number theory and cryptography.
  • Simplifying Fractions: It helps in simplifying fractions by identifying common factors.
Applications:
  • Cryptography: Many encryption systems rely on the difficulty of factoring large numbers.
  • Coding Theory: Prime factorisation is used in error-correcting codes.
  • Computer Science: Used in algorithms for various computational problems.
  • Mathematics: Essential in number theory, algebraic structures, and more.

Understanding Prime Factorization

Prime factorization is the breakdown of a number into prime numbers that can be multiplied together to get the original number. Every positive integer greater than 1 can be expressed this way. For example, the number 60 can be factored into its prime components: 2, 3, and 5. This process is not just a mathematical exercise; it's foundational for many concepts in Mathematics.
