It is a sphenic number, and is the product of three consecutive prime numbers. 105 is the double factorial of 7. It is also the sum of the first five square pyramidal numbers. 105 comes in the middle of the prime quadruplet (101, 103, 107, 109). The only other such odd numbers less than a thousand are 9, 15, 195 and 825. 105 is also a pseudoprime to the prime bases 13, 29, 41, 43, 71, 83 and 97. The distinct prime factors of 105 add up to 15, and so do those of 104, hence the two numbers form a Ruth-Aaron pair under the first definition. 105 is also a number ''n'' for which $n\; -\; 2^k$ is prime, for . (This even works up to $k\; =\; 8$, ignoring the negative sign.) 105 is the smallest integer such that the factorization of $x^n-1$ over Q includes coefficients other than $\backslash pm\; 1$. In other words, the 105th cyclotomic polynomial, Φ105, is the first with coefficients other than $\backslash pm\; 1$. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「105 (number)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
