The question asked was about the strength of gravity exerted by one planet, so a slightly more apposite formula is the one for the gravitational acceleration felt by an object of any mass in free fall:

g=G.M/r²

i.e. it’s independent of the mass of the other object.

Yeah but if you consider force=massacceleration, m2A=gm1m2/r^2 then A=g*m1/r^2 and A is acceleration from gravity which is the same as the formula you posted. Which is independent of the mass of the second object

I assumed the person who posed the question initially could get to this point algebraically.
