How to use fermit's thereom in finding remainder of a number when divided by another number ?
(eg remainder of 52005 when divided by 4010 ?)
(eg remainder of 52005 when divided by 4010 ?)
Fermat's Theorem, also known as Fermat's Little Theorem, is a mathematical theorem that states that if p is a prime number, then for any integer a, a^p is congruent to a (mod p). This means that when a prime number is raised to a power, the remainder of that power divided by the prime number will always be the original number.
Fermat's Theorem is used to find remainders by simplifying the calculation. Instead of dividing a large number by another number to find the remainder, Fermat's Theorem allows us to raise the large number to a smaller power and still get the same remainder. This makes the calculation much easier and faster.
Fermat's Theorem and Euclidean Division are two different methods used to find remainders. While Euclidean Division involves multiple steps of division and subtraction, Fermat's Theorem simplifies the calculation by raising the number to a smaller power. Additionally, Euclidean Division can be used for any number, while Fermat's Theorem only applies to prime numbers.
No, Fermat's Theorem can only be used for prime numbers. This is because the theorem relies on the property of prime numbers that any number raised to a prime number will always have a remainder of the original number when divided by the prime number.
Fermat's Theorem has various applications in fields such as cryptography, number theory, and computer science. It is used in algorithms for encryption and decryption, as well as in the generation of pseudorandom numbers. It is also used in the study of prime numbers and their properties.
