## How do you find the multiplicative inverse of a modulo?

Naive method. A naive method consists of trying all numbers from the set {0,, m – 1}. For every number x from this set, calculate a * x mod m, i.e., the remainder from the division of a * x by m. The modular multiplicative inverse of a modulo m is the value of x for which this remainder is equal to 1.

## How do you do inverse modulo?

A naive method of finding a modular inverse for A ( mod C) is:

- Calculate A * B mod C for B values 0 through C-1.
- The modular inverse of A mod C is the B value that makes A * B mod C = 1. Note that the term B mod C can only have an integer value 0 through C-1, so testing larger values for B is redundant.

## What is the multiplicative inverse of /- 5?

For example, the multiplicative inverse of 5 is 1/ 5.

## What is the multiplicative inverse of answer?

In mathematics, we call the number 1 the multiplicative identity because if we multiple any number by 1, we get that same number as our answer. A multiplicative inverse of a number, x, is a number y, such that if we multiply x times y, then we get the multiplicative identity. That is, x × y = 1.

## What is the multiplicative inverse of 7 in MOD 11?

Then from 7 x≡56( mod11 ), we can cancel 7, obtaining x≡8( mod11 ). Hence, −3 is the inverse of 7 ( mod11 ).

## What is the multiplicative inverse of 7 MOD 120?

The multiplicative inverse of 7 mod 120 * is 103mo – Gauthmath.

## What is the multiplicative inverse of 1?

The multiplicative inverse of 1 is 1. The multiplicative inverse of 0 is not defined. The multiplicative inverse of a number x is written as 1 /x or x^{–} ^{1}. The multiplicative inverse of a mixed fraction can be obtained by converting the mixed fraction into an improper fraction and determining its reciprocal.

## Which is not inverse of 2 modulo 17?

The Euclidean algorithm to compute gcd( 17, 2 ) performs the following step: 17 = 8 · 2 +1 5 Page 6 The next gcd is gcd( 2,1), which is just 1. Therefore 1· 17 −8· 2 = 1, so (taking both sides mod 17 ) (−8) · 2 = 1. Therefore −8 is an inverse of 2 mod 17. Thus a has no inverse (i.e., b) mod m.

## What is the multiplicative inverse of 1 3?

Likewise the multiplicative inverse of 1 1/3 is 3/4.

## Does 0 have a multiplicative inverse?

The short answer is that 0 has no multiplicative inverse, and any attempt to define a real number as the multiplicative inverse of 0 would result in the contradiction 0 = 1.

## What is the multiplicative inverse of 1 6?

Answer: The multiplicative inverse of -1/6 is 6/-1 or -6. plzz like the answer..

## What is the multiplicative inverse of 4 7?

i.e, multiplicative inverse of 4/7 is 7/4.

## What is the multiplicative inverse of 15?

It was really that simple! The multiplicative inverse of a number is that number as the denominator and 1 as the numerator. When we multiply 15 and 1/ 15, we get 1.

## What is the inverse of 50%?

Thus, the answer to “What is the additive inverse of 50?” is – 50.

## What is the multiplicative inverse of 5 3?

Answer: multiplicative inverse means the reciprocal of a given fraction. so here the fraction is 5/3 and its reciprocal is 3/5 which is the multiplicative inverse of 5/3.
