We've used the gcd/lcm formula with prime factorisation and a fact that max⁡{x,y}+min⁡{x,y}=x+y\max \{ x,y \}+ \min \{ x,y \}=x+ymax{x,y}+min{x,y}=x+y to prove gcd⁡(m,n)⋅lcm(m,n…

Let us first consider the following: gcd(a,b)=1 ⟹ lcm(a,b)=abgcd(a, b) = 1 \implies lcm(a, b) = a bgcd(a,b)=1⟹lcm(a,b)=ab lcm(ac,bc)=clcm(a,b)lcm(a c, b c) = c lcm(a, b)lcm(ac,b…
