   en.wikipedia.org/wiki/400_(number)

   432 = 2 4 × 3 3 = 4 2 × 3 3, the sum of four consecutive primes (103 + 107 + 109 + 113), a Harshad number, a highly totient number, [40] an Achilles number and the sum of totient function for first 37 integers. 432! is the first factorial that is not a Harshad number in base 10. 432 is also three-dozen sets of a dozen, making it three gross.

3. List of prime numbers - Wikipedia

   en.wikipedia.org/wiki/List_of_prime_numbers

   This is a list of articles about prime numbers. A prime number (or prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid's theorem, there are an infinite number of prime numbers. Subsets of the prime numbers may be generated with various formulas for primes.

4. 200 (number) - Wikipedia

   en.wikipedia.org/wiki/200_(number)

   The number appears in the Padovan sequence, preceded by 86, 114, 151 (it is the sum of the first two of these). [1] The sum of Euler's totient function φ(x) over the first twenty-five integers is 200. 200 is the smallest base 10 unprimeable number – it cannot be turned into a prime number by changing just one of its digits to any other digit.

5. Table of prime factors - Wikipedia

   en.wikipedia.org/wiki/Table_of_prime_factors

   A factorial x! is the product of all numbers from 1 to x. The first: 1, 2, 6, 24, 120, 720, 5040, 40320, 362880, 3628800, 39916800, 479001600 (sequence A000142 in the OEIS). 0! = 1 is sometimes included. A k-smooth number (for a natural number k) has its prime factors ≤ k (so it is also j-smooth for any j > k).
