What grade did you learn common factor and common multiple?
Multiplication and factor are the knowledge points in the fifth grade of primary school.

Related concepts:

A factor is a number divisible by a number, and a common factor is a number divisible by two or more numbers at the same time. By studying the common factor, we can understand the meaning of the factor more deeply and use the concepts of factor and multiple more flexibly to solve practical problems.

Benefits of learning common factors:

Learning common factors is helpful to improve our mathematical thinking ability and logical thinking ability. In the process of finding common factors, we need to observe, compare and analyze the given numbers to find out their common factors. This requires us to use mathematical thinking and logical thinking for reasoning and judgment, and cultivate our own thinking ability and problem-solving ability.

Learning common factors can help us to master other mathematical knowledge more easily. Common factor is an important concept in number theory, which is closely related to the concepts of greatest common factor and least common multiple. By studying common factors, we can better understand the relationship between these concepts and lay a solid foundation for the follow-up research.

The benefits of learning mathematics:

1. Improve logical thinking ability

Mathematics is a subject that requires strict logical thinking. Learning mathematics can cultivate our logical thinking ability and improve our ability to analyze and solve problems.
