a(n) is the smallest number such that: prime(1)^n | a(n), prime(2)^n | a(n)+1,..., prime(n)^n | a(n)+n-1.
EXAMPLE
a(1) = 2 as 2 is divisible by 2^1 ;
a(2) = 8 as 8 and 9 are divisible by 2^2 and 3^2 respectively ;
a(3) = 21248 as 21248, 21249 and 21250 are divisible by 2^3, 3^3 and 5^3 respectively.
