isCoprime

Test if two numbers are coprime.

Two integers a and b are said to be coprime (or relatively prime or mutually prime) if the only positive integer that divides both of them is 1.

Installation

npm install @stdlib/math-base-assert-is-coprime

Usage

var isCoprime = require( '@stdlib/math-base-assert-is-coprime' );

isCoprime( a, b )

Tests if two numbers are coprime.

var bool = isCoprime( 14.0, 15.0 );
// returns true

bool = isCoprime( 14.0, 21.0 );
// returns false

Examples

var isCoprime = require( '@stdlib/math-base-assert-is-coprime' );

var bool = isCoprime( 5.0, 7.0 );
// returns true

bool = isCoprime( 5.0, 15.0 );
// returns false

bool = isCoprime( NaN, NaN );
// returns false
