Solution

The correct option is D 84
The lowest number which will be divisible by both of these numbers is the LCM of these numbers.
To find the LCM of the numbers first we will find out its prime factors
The factors of 7: 1, 7

The factors of 12: 1, 2, 3, 4, 6, 12

Since the only common factor is 1, the given two numbers are co-prime.
The LCM of these numbers is their product.
$∴$ The required number is 7 $\times$ 12 = 84.
