We need to know what the least common multiple is and how to find it. The least common multiple (LCM) is the least common multiple of two or more integers. The common method to find LCM of two numbers is to use their greatest common divisor (GCD).
The formula is: a×b=GCD(a, b)×LCM(a, b). Suppose these two numbers are a and b, we know that a×b=GCD(a, b)× 180. In order to find out A and B, we need more information or restrictions. Because only LCM is given, there are countless pairs of A and B that can meet this condition.
But if we assume that A and B are relative prime numbers (that is, there is no common divisor between them except 1), then GCD(a, b)= 1. In this way, a and b can be solved, so we assume that a and b are relative prime numbers, so: a×b= 1× 180.
The secret of learning mathematics:
1. Establish the basic knowledge system of mathematics: Mathematics is a highly systematic subject, which is based on a series of basic concepts, principles and methods. If you want to learn mathematics well, you need to lay a good foundation and establish a complete knowledge system. This includes mastering basic mathematical terms, symbols and operation rules, understanding various mathematical concepts and principles, and mastering common mathematical methods. Establishing the basic knowledge system of mathematics requires constant study and practice, patience and perseverance.
2. Pay attention to practice and thinking: Mathematics is a highly practical subject. If you really want to master mathematics knowledge, you need to do a lot of practice and thinking.
Practice helps to consolidate the knowledge learned and cultivate the ability of calculation and reasoning. Thinking helps to deepen the understanding of mathematical principles and methods and cultivate the ability of independent thinking and problem solving. When doing the problem, you need to carefully examine the problem, analyze the ideas and solving steps, and pay attention to summing up experiences and lessons. When thinking about problems, we need to try a variety of ideas and methods and constantly develop our thinking.
3. Cultivate interest and curiosity: Mathematics is a subject full of fun and challenges. If you want to learn math well, you need to cultivate interest and curiosity. Interest in mathematics can help maintain the motivation and enthusiasm for learning, while curiosity can drive you to explore unknown mathematical fields and problems. Interest and curiosity can be cultivated by reading math books, participating in math competitions and discussions, and solving math problems in life.
