### Extended Euclidean Algorithm and Inverse Modulo Tutorial

• In some cases, the meaning of opposite is expressed by a word inverse in mathematics. The product of two quantities equals to one is actually calculated by the multiplication. According to these two considerable factors, one quantity is called a multiplicative inverse of the remaining quantity
• For example, find the multiplicative inverse of 2, mod 7. [G,D] = gcd(2,7) G = 1. D =-3. The second argument will be a multiplicative inverse of 2, as long as G is 1. G is the GCD of the two numbers, and if they are relatively prime, then G will be 1. If so, then D will be a multiplicative inverse
• Before we go over how multiplicative inverses work for complex numbers, let's quickly review how multiplicative inverses work for real rational numbers like the ones below. $$2 \text{ and } \frac 1 2$$ because $$2 \cdot \frac 1 2 = \red 1$$ The multiplicitive inverse of any complex number $$a + bi$$ is $$\frac{1}{ a + bi}$$
• The Multiplicative Inverse Axiom states that the product of a real number and its multiplicative inverse is 1. Every real number has a unique multiplicative inverse. The reciprocal of a nonzero number is the multiplicative inverse of that number. Reciprocal of x is 1/x
• The multiplicative inverse of a is an integer x such that ax 1 (mod n); or equivalently, an integer x such that ax = 1 + k n for some k. If we simply rearrange the equation to read ax k n = 1; then the equation can be read as The integer a has a multiplicative inverse

### What is the multiplicative inverse of 0/1? - Brainly

In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1.The multiplicative inverse of a fraction a/b is b/a.For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1. The modular multiplicative inverse is an integer 'x' such that. a x ≡ 1 (mod m) The value of x should be in {0, 1, 2, m-1}, i.e., in the ring of integer modulo m.
