What is Modular Multiplication?
Modular multiplication is a type of multiplication performed under modular arithmetic. In simpler terms, it's multiplication where the result is always reduced to fit within a specific range, determined by the modulus.
When we calculate (a × b) mod m, we are finding the remainder when the product of 'a' and 'b' is divided by 'm'. This operation is fundamental in various fields like cryptography, computer science, and number theory.
Formula:
The formula for modular multiplication is expressed as:
- a, b: The numbers being multiplied.
- m: The modulus, a positive integer.
- mod: The modulo operation, which gives the remainder of a division.
Example:
For example, to calculate (7 × 3) mod 5:
- Multiply 7 and 3 to get 21.
- Divide 21 by 5. The remainder is 1.
- So, (7 × 3) mod 5 = 1.
