How does mathjs.gcd work?

mathjs.gcd function computes the greatest common divisor (GCD) of two or more numbers using the Euclidean algorithm. It repeatedly divides the greater number by the smaller number and keeps doing this until the remainder becomes zero. The last non-zero remainder is the GCD.

math.round(a) // round to nearest int
math.ceil(a); // round in positive direction
math.fix(a) // round towards zero

// factors & multiples
math.gcd(a, b) // greatest common denominator
math.lcm(a, b) // least common multiple

// stats
math.max(numbers);

const math = require("mathjs");

const result = math.gcd(24, 36, 48);
console.log(result); // output: 12

In this example, we first import the mathjs library and then use the math.gcd function to find the greatest common divisor of the numbers 24, 36, and 48. The result is 12, which is then printed to the console.
