I am aiming to prove that:(adsbygoogle = window.adsbygoogle || []).push({});

lcm(ab,ad)=a[lcm(b,d)]

I am not really sure where to start. So I simply want to prove that a divides lcm(ab,ad)? Or that if a divides b and a divides d then it will divide the lcm of (ad,ad)? Nonetheless, I am still not sure as to where to start? Any tips?- Thanks
