The positive integer k has exactly two positive prime factors, 3 and 7. If k has a total of 6 positive factors, including 1 and k, what is the value of k?
(1) 3^2 (3 squared) is a factor of k.
(2) 7^2 (7 squared) is NOT a factor of k.
Help would be appreciated! Thanks.
Best regards,
ST
Hint :- if k has 6 factors
then k must be 3^2 *7
or k = 3* 7^2
now try yourself
