Multiple political parties are most common in a parliamentary system. In this system, parties often form coalitions to achieve a majority, reflecting a wider range of political views and interests. This contrasts with a two-party system, where two dominant parties typically compete for power. Countries like Germany and India exemplify parliamentary systems with multiple active political parties.
Double and multiple star systems are fairly common, but I am not sure whether there is enough information to state which one is more common. There is a possible selection bias, and the answer will depend on whether you include star clusters in "multiple systems".
False. Two-party systems are actually most common in English-speaking countries, such as the United States and the United Kingdom. French-speaking countries, like France and Canada, often have multiparty systems with multiple major political parties.

There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
The two most common systems of units are cgs and SI systems
"most common multiple" is not a recognised mathematical term. 48 is a common multiple, but it is not the Least Common Multiple (LCM).
The two most common party systems in English-speaking countries are the two-party system, where two major parties dominate the political landscape (e.g., Democrats and Republicans in the U.S., Conservatives and Labour in the UK), and the multi-party system, where several parties compete for power and representation (e.g., Canada, Australia).
The most common multiple of any set of integers is infinite.
If you mean the lowest common multiple then it is 280
