| |
| '''39''' ('''thirty-nine''') is the [[natural number]] following [[38 (number)|38]] and preceding [[40 (number)|40]].
| |
| | |
| == In mathematics ==
| |
| [[File:F26A graph.svg|thumb|right|200px|The [[F26A graph]] has 39 edges, all equivalent.]]
| |
| '''Thirty-nine''' is the sum of consecutive [[Prime_number|primes]] (3 + 5 + 7 + 11 + 13) and also is the product of the first and the last of those consecutive primes. Among small semiprimes only three other integers (10, 155, and 371) share this attribute. 39 also is the sum of the first three powers of [[3 (number)|3]] (<math>3^1 + 3^2 + 3^3</math>). Given 39, the [[Mertens function]] returns [[0 (number)|0]].
| |
| | |
| 39 is the smallest natural number which has three partitions into three parts which all give the same product when multiplied: {25, 8, 6}, {24, 10, 5}, {20, 15, 4}.
| |
| | |
| 39 is the 12th distinct [[semiprime]] and the 4th in the {3.q} family. It is the last member of the third distinct biprime pair (38,39).
| |
| | |
| 39 has an [[aliquot sum]] of 17 which is itself a prime. 39 is the 4th member of the 17-aliquot tree. It is a [[Perfect totient number]]
| |
| | |
| The thirteenth [[Perrin number]] is 39, which comes after 17, 22, 29 (it is the sum of the first two mentioned).
| |
| | |
| Since the greatest prime factor of 39<sup>2</sup> + 1 = 1522 is 761, which is obviously more than 39 twice, 39 is a [[Størmer number]].
| |
| | |
| The [[F26A graph]] is a [[symmetric graph]] with 39 edges.
