%N a(1)= 7, a(n) = least prime obtained by prefixing the digits of a multiple of n to a(n-1).
%C Digits of a(n) can be partitioned from (least siginifacnt one) right to left into multiples of 1 to n. a(5) = 5012347 ===> 50, 12, 3, 4, 7.
%e a(3) = 347 and a(4) = 12347 is obtained by prefixing 12 to 347.
