Answer» Correct Answer - Option 4 : 2793 Given: Our given expression is 7x + 7x + 1 + 7x + 2 Concept used: A natural number is the counting number starting from 1. Calculation: Our given expression is 7x + 7x + 1 + 7x + 2 ⇒ 7x(1 + 7 + 72) ⇒ 7x(57) Taking the value of x = 1, 2, 3, … and so on then, The number is 399, 2793, … and so on So, the greatest divisor when x = 1, will be 399. When x = 2, greatest divisor will be 2793 ...and so on. ∴ The correct answer from the option is 2793. |
