34 (thirty-four) is the natural number following 33 and preceding 35.
[edit] In mathematics34 is the ninth distinct semiprime and has four divisors including unity and itself. Its neighbors, 33 and 35 also are distinct semiprimes having four divisors each, and 34 is the smallest number to be surrounded by numbers with the same number of divisors as it has. It is also in the first cluster of three distinct semiprime, being within; 33,34,35, the next such cluster of semiprimes is; 85,86,87. It is the ninth Fibonacci number and a companion Pell number. Since it is an odd-indexed Fibonacci number, 34 is a Markov number, appearing in solutions with other Fibonacci numbers, such as (1, 13, 34), (1, 34, 89), etc. This number is the magic constant of a 4 by 4 normal magic square Thirty-four is a heptagonal number. It has the aliquot sum, 20, in the following descending sequence 34,20,22,14,10,8,7,1. and it is the 6th composite member of the 7-aliquot tree. There is no answer to the equation φ(x) = 34, making 34 a nontotient. Nor is there an answer to the equation x - φ(x) = 34, making 34 a noncototient. [edit] In science
