The Uniswap V2 factory contract is arguably the core contract of the protocol. Its primary purpose is to create pools (called pairs in the contract). To do so, it uses the create2 opcode, which is capable of deploying contracts with deterministic addresses. This is useful to calculate the address of the pool of a pair of tokens (even off-chain).

It is the core Uniswap functionality. These are all the interfaces that the contract needs to know about, either because the contract implements them ( IUniswapV2Pair and UniswapV2ERC20) or because it calls contracts that implement them. This contract inherits from UniswapV2ERC20, which provides the the ERC-20 functions for the liquidity tokens.
