Benchmark: Compare GCD_ - MeasureThat.net

Script Preparation code:

function gcd(a, b){
  var divisor = 2, 
      greatestDivisor = 1;

  if (a < 2 || b < 2)
     return 1;
  
  while(a >= divisor && b >= divisor){
   if(a %divisor == 0 && b% divisor ==0){
      greatestDivisor = divisor;      
    }
   divisor++;
  }
  return greatestDivisor;
}

function gcd1(a,b){
    var divisor = a < b ? a : b;  	
    
    if(a < 2 || b < 2){
        return 1;
    }
    
    while(divisor > 0){
        if(a % divisor === 0 && b % divisor === 0){
            return divisor;
        }
        divisor--;
    }
}

function gcd2(a, b){
    var x;
    
    while(b !== 0){
        x = a % b;
        a = b;
        b = x;
    }
    
    return a;
}

function gcd3(a, b){
    if(b === 0)
        return a;
    return gcd3(b, a % b);
}
