5×1×7
5×1×7 refers to a mathematical expression involving three positive integers: five, one, and seven. The multiplication operation is applied sequentially. First, 5 is multiplied by 1, which results in 5. Then, this intermediate product of 5 is multiplied by 7, yielding a final result of 35. Therefore, the value of the expression 5×1×7 is 35. This calculation is a straightforward example of the associative property of multiplication, where the order of grouping does not affect the final product. In this case, (5×1)×7 = 5×(1×7) = 35. The numbers 5, 1, and 7 are prime numbers, except for 1 which is neither prime nor composite. The product 35 is a composite number, with prime factors 5 and 7. This expression could appear in various contexts, such as in geometry to calculate the volume of a rectangular prism with dimensions 5 units by 1 unit by 7 units.
