Answer:
Step-by-step explanation:
Factorize of the above numbers :
12 = 2^{2} × 3
16 = 2^{4}
18 = 3^{2} × 2
21 = 7 × 3
28 = 2^{2} × 7
L.C.M. = 2^{4} × 3^{2} × 7
= 16× 9 × 7
= 1008
but 1008 + 7 = 1015
Ya, LCM of the numbers is 1008 which is equal to the smallest no diminished by 7,
So 1008 = x-7,
Then smallest no, x=1008+7.
That's why we are added with 7
