1, enumeration method: list all factors of this number one by one. For example, if the factor of 24 is required, the numbers 1, 2, 3, 4, 6, 8, 12, 24 can be listed, all of which are factors of 24.

2. Decomposition prime factor method: decompose this number into the product of several prime numbers, and each prime number is a factor of this number. For example, if the prime factor of 60 is decomposed into 2×2×3×5, then the factor of 60 is 1, 2,3,4,5,6, 10, 12,15,20,30,60.

3. Factor pair method: If a number has factors A and B, then a×b is the value of this number. So, you can find all the factor pairs of this number and multiply them by two to get all the factors of this number. For example, if you want to find the factor of 24, you can find its factor pairs and multiply them by two to get the factor of 1, 2, 3, 4, 6, 8, 12, 24.

4. Multiplication: If one number is a factor of another number, then the multiple of this number is also a factor of that number. So you can find a factor of this number and list all its multiples, which are all factors of this number.

The benefits of learning mathematics

People who are good at math are relatively smart and savvy, and they can show their advantages in dealing with people. The faster you think, the more ways and ideas you have. Cambridge, majoring in financial mathematics at Carnegie Mellon University in the United States, said that studying mathematics has brought her mental exercise and made me pay more attention to the rigor of thinking in my life.

For example, before solving a problem, I like to divide it into several sections, and each section is divided into several steps, so that I can dig slowly like a branch instead of thinking in confusion in front of a pile of data. Mathematics is the foundation of other disciplines, and it is easier for people who learn mathematics well to get into other disciplines. Learning software, computer, finance and other engineering majors is even more handy.
