The purpose of the present paper is to give a sharpened and corrected version of a theorem of carmichael theorem 1. Sylvester coined the term totient for this function, so it is also referred to as eulers totient function, the euler totient, or eulers totient. Abraham lincoln first made his name in the lincoln. Informally, we can understand the formula as follows. Your user files in euler files and your settings in. In other words, it is the number of integers k in the range 1. In number theory, eulers totient function counts the positive integers up to a given integer n that. From this product we see that eulers constant is deeply related to the gamma function and the poles are clearly the negative or null integers.
