The factor x factor = product formula is a×b=c(a, b and c are all integers). The formula for multiplying a factor by a factor equals a product is a×b=c(a, b and c are all integers). It should be noted that this relationship only holds if the dividend, divisor and quotient are integers and the remainder is zero. Conversely, we call C a multiple of A and B. When learning factors and multiples, primary school mathematics does not consider 0.

A detailed introduction to the formula of factor × factor = product

In mathematics, the relationship between factor × factor = product is called multiplication. The multiplication formula can not only be used smoothly from left to right, but also be multiplied by polynomials. Can also be used from right to left, factorization. Factorization and polynomial multiplication are inverse operations. Remember some important formula variants and their inverse division.

Multiplicative commutative law, multiplicative commutative law is the multiplication of two numbers, the position of commutative factors and their products are unchanged. A×b=b×a is called multiplicative commutative law.

The law of multiplicative association is the multiplication of three numbers. Multiply the first two numbers and then another number, or multiply the last two numbers and then multiply another number, and the product remains the same.

The main formula is a×b×c=a×(b×c), which can change the operation order in multiplication. In daily life, the application of multiplicative associative law is not extensive, but mainly plays a simple role in some complex operations.
