Factor means that the quotient (b≠0) of the integer A divided by the integer B is exactly an integer with no remainder, so B is a factor of A. In addition, if a*b=c(a, B and C are all integers), then A and B are called factors of C.

It should be noted that the relationship can only be established when the dividend, divisor and quotient are integers and the remainder is zero. On the contrary, c is called a multiple of a and b, but in fact, factors are generally defined on integers: let a be an integer and b be a non-zero integer. If there is an integer Q that makes A=QB, then B is said to be a factor of A. ..

Introduction to mathematics

Mathematics is a discipline that studies the concepts of quantity, structure, change, space and information, and belongs to a formal science from a certain point of view. Mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.

In the development of human history and social life, mathematics also plays an irreplaceable role, and it is also an indispensable basic tool for studying and studying modern science and technology.

Mathematics is a universal means for human beings to strictly describe the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.

Mathematics plays an irreplaceable role in the development of human history and social life, and it is also an indispensable basic tool for studying and studying modern science and technology.
