Answer :

the digitsum of the given number should be divisible by 3.
here the digitsum is=6+5+2+0+6+a=19+a.
after 19 the least number divisible by 3 is=21.
so, a=2.

We know that if the sum of digits of a no. is divisible by 3 then it also divisible by 3.

Here,

6+5+2+0+a+6 = 19 + a

  • Least possible value of a = 2.
