lcm

Compute the least common multiple (lcm).

The least common multiple (lcm) of two non-zero integers a and b is the smallest positive integer that is divisible by both a and b. The lcm is also known as the lowest common multiple or smallest common multiple and finds common use in calculating the lowest common denominator (lcd).

Usage

var lcm = require( '@stdlib/math/base/special/lcm' );

lcm( a, b )

Computes the least common multiple (lcm).

var v = lcm( 48, 18 );
// returns 144

If either a or b is 0, the function returns 0.

var v = lcm( 0, 0 );
// returns 0

v = lcm( 2, 0 );
// returns 0

v = lcm( 0, 3 );
// returns 0

Both a and b must have integer values; otherwise, the function returns NaN.

var v = lcm( 3.14, 18 );
// returns NaN

v = lcm( 48, 3.14 );
// returns NaN

v = lcm( NaN, 18 );
// returns NaN

v = lcm( 48, NaN );
// returns NaN

Examples

var randu = require( '@stdlib/random/base/randu' );
var round = require( '@stdlib/math/base/special/round' );
var lcm = require( '@stdlib/math/base/special/lcm' );

var a;
var b;
var v;
var i;

for ( i = 0; i < 100; i++ ) {
    a = round( randu()*50 );
    b = round( randu()*50 );
    v = lcm( a, b );
    console.log( 'lcm(%d,%d) = %d', a, b, v );
