The expression "2 × 3 × 5 × 11" represents the multiplication of four prime numbers: 2, 3, 5, and 11. Prime numbers are natural numbers greater than 1 that have no positive divisors other than 1 and themselves. This specific multiplication results in the product of 330. When you multiply these numbers together, you can think of it as finding the total number of combinations or arrangements that can be formed using these factors. The product, 330, can also be factored back into its prime components, illustrating the fundamental theorem of arithmetic, which states that every integer greater than 1 can be uniquely factored into prime numbers.
