Which one of the following is the largest divisor of 7x + 7x + 1 + 7x + 2, if x is any natural number? (from the given option)1. 72. 573. 3994. 2793

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.
