(1) If our divisor remained unchanged, the calculation for the average would give us 95.00.

(2) The greatest common divisor

(3) All positive integers n have at least one prime divisor: if n is prime, then it is its own prime divisor .

(4) After graduating in 1939 he began to work for his doctorate on the problem of divisors of almost periodic polynomials.

(5) Prime numbers are integers with no divisors other than 1 and themselves.

(6) Influenced by Gauss, Smith's most important contributions are in number theory where he worked on elementary divisors .

(7) A pair of amicable numbers is a pair like 220 and 284 such that the proper divisors of one number sum to the other and vice versa.

(8) Its proper divisors are 1, 2, 4, 7, and 14, and the sum of those divisors is 28.
