Which property ensures that the grouping of factors does not affect their product?

The property that ensures the grouping of factors does not affect their product is the Associative Property of Multiplication. This property states that when multiplying three or more numbers, the way in which the numbers are grouped does not change the result. For example, if you take the numbers 2, 3, and 4, you can group them in different ways: (2 x 3) x 4 = 6 x 4 = 24, or 2 x (3 x 4) = 2 x 12 = 24. In both cases, the product remains the same, which demonstrates the essence of the Associative Property.

Other properties, such as the Commutative Property, refer to changing the order of the factors rather than their grouping. The Distributive Property involves distributing a multiplication over addition or subtraction, and the Zero Property states that any number multiplied by zero equals zero. These properties have different significance in multiplication but do not pertain to how factors are grouped.
