Characteristics of factors in mathematics
Factor means that the quotient of an integer A divided by an integer B and B is not equal to 0, so we say that B is a factor of A, and if A times B equals C and abc is an integer, then we say that A and B are factors of C. It should be noted that this relationship is only established when the dividend, divisor and quotient are integers with a remainder of zero. Conversely, we call C a multiple of A and B. When learning factors and multiples, primary schools
1 has only a positive factor of 1, so it is neither a prime number nor a composite number. If A is a factor of B and A is a prime number, A is said to be a prime factor of B. For example, 235 is a prime factor of 30. 6 is not a prime number, so it doesn't count. 7 is not a factor of 30, so it is not a prime factor. Two nonzero natural numbers whose common factor is only 1 are called coprime numbers.
