5×11×17+3×11 is a composite number , we need to demonstrate that it can be factored into the product of two or more integers, each greater than 1. Let's start with the expression If any number can be represented in the form of product of prime numbers then that number is composite number . Hence , ( 17 x 11 x 2 ) + ( 17 x 11 x 5 ) is a composite number . Given; 11×13×15×17+17 is a composite number To Find; Why it is a composite number Solution; Composite numbers are the numbers that don't have a common factor other than 1 11×13×15×17+17 = 36465 + 17 = 36482 Now 36482 is an even number but is formed by-product of various odd numbers Hence it is a composite number Answer: Step-by-step explanation: it will become 17"2 (21"15"11"1+1)so now clearly on multiplying we get a number which has 17 2 as it factors therfore it is composite
