Step-by-step explanation:

Take LCM for the values given values are 12,18,21,31

For 12, LCM = 1,2,2,3

For 18 LCM = 1,2,3,3

For 21 LCM = 1,3,7

For 31 LCM = 1,31

After taking LCM the values may come as 7812 hence this number is divisible by the above-given numbers

By multiplying with 2 you may get the answer  

i.e. 7812 $\times$ 2 = 15624
