2. Table of prime factors - Wikipedia

   en.wikipedia.org/wiki/Table_of_prime_factors

   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). m is smoother than n if the largest prime factor of m is below the largest of n.

3. Prime power - Wikipedia

   en.wikipedia.org/wiki/Prime_power

   In mathematics, a prime power is a positive integer which is a positive integer power of a single prime number. For example: 7 = 7 1, 9 = 3 2 and 64 = 2 6 are prime powers, while 6 = 2 × 3, 12 = 2 2 × 3 and 36 = 6 2 = 2 2 × 3 2 are not. The sequence of prime powers begins:

4. Number theory - Wikipedia

   en.wikipedia.org/wiki/Number_theory

   German mathematician Carl Friedrich Gauss (1777–1855) said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics." [ 1 ] Number theorists study prime numbers as well as the properties of mathematical objects constructed from integers (for example, rational numbers ), or defined as generalizations of the ...

5. 120 (number) - Wikipedia

   en.wikipedia.org/wiki/120_(number)

   The sum of its factors (including one and itself) sum to 360, exactly three times 120. Perfect numbers are order two ( 2-perfect ) by the same definition. 120 is the sum of a twin prime pair (59 + 61) and the sum of four consecutive prime numbers (23 + 29 + 31 + 37), four consecutive powers of two (8 + 16 + 32 + 64), and four consecutive powers ...

9. Prime omega function - Wikipedia

   en.wikipedia.org/wiki/Prime_omega_function

   In number theory, the prime omega functions and () count the number of prime factors of a natural number . The number of distinct prime factors is assigned to () (little omega), while () (big omega) counts the total number of prime factors with multiplicity (see arithmetic function).
