The sum of two positive integers a and b is 80. What is the largest possible value of gcd(a,b) + lcm(a,b)?
a=1; b=1;d=a+b;f=gcd(a,b)+lcm(a,b); if(d==80, goto5, goto6);printf, a, b; a++;if(a<200, goto2, 0);a=1;b++;if(b<200, goto2, discard=0;
a = 39, b = 41
a + b = 39 + 41 = 80
GCD(39, 41) = 1
LCM(39, 41) =1599
GCD + LCM =1 + 1599 =1600
