    38! − 1 yields 523 022 617 466 601 111 760 007 224 100 074 291 199 999 999 which is the 16th factorial prime. [2] There is no answer to the equation φ(x) = 38, making 38 a nontotient. [3] 38 is the sum of the squares of the first three primes. 37 and 38 are the first pair of consecutive positive integers not divisible by any of their digits.

    If none of its prime factors are repeated, it is called squarefree. (All prime numbers and 1 are squarefree.) For example, 72 = 2 3 × 3 2, all the prime factors are repeated, so 72 is a powerful number. 42 = 2 × 3 × 7, none of the prime factors are repeated, so 42 is squarefree.

  9. Euler's factorization method - Wikipedia

    en.wikipedia.org/wiki/Euler's_factorization_method

    The great disadvantage of Euler's factorization method is that it cannot be applied to factoring an integer with any prime factor of the form 4k + 3 occurring to an odd power in its prime factorization, as such a number can never be the sum of two squares.
