Background
The House of Representatives has 435 voting members. The number is not in the Constitution; Congress fixed it by statute in 1929 after decades of growth, and it has stayed there ever since even as the population more than tripled. Seats are divided among the states by population using the census taken every ten years, a process called apportionment, and each state then draws its share into districts. Every state gets at least one seat no matter how small. Alongside the 435 voting members sit several non-voting delegates representing the District of Columbia and the territories, who may debate and vote in committee but not on final passage, which is why the question specifies voting members.
