23×40

23×40 denotes the product of the integers 23 and 40. In mathematics, the symbol × is the multiplication sign, so the expression represents multiplying 23 by 40, yielding the value 920.

Prime factorization and arithmetic properties: 23 is a prime number and 40 factors as 2^3 × 5. Therefore 23×40 = 2^3 × 5 × 23 = 920. Because 23 does not divide 40, the two factors are coprime. The result, 920, is an even number and a composite number.

Divisors: Based on the prime factorization 2^3 × 5 × 23, 920 has 16 positive divisors. These include 1, 2, 4, 8, 5, 10, 20, 40, 23, 46, 92, 184, 115, 230, 460, and 920. The list reflects all combinations of the prime factors.

Geometric and practical interpretations: In geometry, 23×40 can represent the area of a rectangle with side lengths of 23 and 40 units, giving 920 square units. In broader contexts, the expression is a simple example used to illustrate multiplication, scaling, and basic factorization.

Summary: 23×40 is the straightforward product of 23 and 40, equal to 920, with a prime factorization of 2^3 × 5 × 23 and a set of 16 divisors. It commonly appears in arithmetic, geometry, and introductory algebra as a concrete instance of multiplication.
