75x(3y)2 and 100xy both have factors of * * * * * It would appear that the question is looking for the GCF of 75x3, y2 and 100xy. If that is the case, the answer is 1.
Oh, dude, the greatest common factor of 75x^3y^2 and 100xy is 25xy. Like, you just gotta find the largest number that divides both terms evenly, and in this case, it's 25xy. Easy peasy lemon squeezy.
GCF(75x3, y2, 100xy) = 1 However, GCF(75x3y2, 100xy) = 25xy
