5986 = 2 x 41 x 73

the digits of n and the prime factorization of n

are from the set 1 to 9 with each digit occurring exactly __one time__.

28651 = 7 x 4093

the digits of n and the prime factorization of n

are from the pandigital set 0 to 9 with each digit occurring exactly __one time__.

14368485 = 3 x 5 x 17 x 29 x 29 x 67

the digits of n and the prime factorization of n

are from the set 1 to 9 with each digit occurring exactly __two times__.

40578660 = 2 x 2 x 3 x 3 x 5 x 17 x 89 x 149
