How do you find the multiplicative inverse of a number in C?

Program 233:To Print Multiplicative Inverse of a Number

  1. This program starts with initializing :
  2. printf(“Enter number to get multiplicative Inverse\n”); scanf(“\%d”,#); Taking input from user(Let it be 7)
  3. Logic of this program is MI=((I*26)+1)/num .
  4. For example: let I is 1 then MI=27/7 which is not integer.

How do you find the multiplicative inverse in Java?

The multiplicative inverse or simply the inverse of a number n, denoted n^(−1), in integer modulo base b, is a number that when multiplied by n is congruent to 1; that is, n × n^(−1) ≡ 1(mod b). For example, 5^(−1) integer modulo 7 is 3 since (5 × 3) mod 7 = 15 mod 7 ≡ 1.

How do you do modular division in C++?

C++ provides the modulus operator, \%, that yields the remainder after integer division. The modulus operator can be used only with integer operands. The expression x \% y yields the remainder after x is divided by y. Thus, 7 \% 4 yields 3 and 17 \% 5 yields 2.

What is modular inverse?

Modular inverse. The inverse of a number modulo is a number such that . It exists (and is unique if exists) if and only and are relatively prime (that is, ). In particular, if is a prime, every non-zero element of has an inverse (thus making it an algebraic structure known as field).

What is an example of a multiplicative inverse?

In other words, a reciprocal is a fraction flipped upside down. Multiplicative inverse means the same thing as reciprocal. For example, the multiplicative inverse (reciprocal) of 12 is and the multiplicative inverse (reciprocal) of is . Note: The product of a number and its multiplicative inverse is 1.

What is the multiplicative inverse of a matrix?

The multiplicative inverse of a real number is the number that yields 1 (the identity) when multiplied by the original number. is the multiplicative inverse of a, because a× = 1. Most matrices also have a multiplicative inverse. In other words, for the majority of matrices A, there exists a matrix A-1 such that AA-1 = I and A-1A = I.

What is an inverse property of multiplication?

Inverse property of multiplication states that every non-zero number “a”, when multiplied by “1/a” gives 1 as the answer. Here 1 is the identity element for multiplication and 1/a of the number is inverse of multiplication.
