 OFFSET 0,2 COMMENTS A number n is in the sequence if it has only noncomposite digits (1,2,3,5,7) and a prime p divides n if and only if p is a digit of n. No other terms below 10^13. No more terms < 10^100. - David Wasserman, Jan 04 2005 LINKS EXAMPLE 131712 is a member because 131712 = 2*2*2*2*2*2*2*3*7*7*7; the prime factors are digits and the digits are factors.
