A.

476

B.

501

C.

567

D.

528

Correct option is D

Given:

To find the smallest natural number divisible by 16, 88, 12, and 22.

Concept Used:

The smallest natural number divisible by a set of numbers is the Least Common Multiple (LCM) of those numbers.

Solution:

Prime factorization of the numbers:

16 = 242^4​​

88 = 23×112^3 \times 11​​

12 = 22×32^2 \times 3​​

22 = 2×112 \times 11​​

LCM = 24×31×111=16×3×112^4 \times 3^1 \times 11^1 = 16 \times 3 \times 11​ = 528
