Webunderstanding of divisibility in other settings in algebra. That is why it is best to regard De nition2.1, which makes no reference to fractions, as the correct de nition of divisibility. The following three theorems about divisibility are simple applications of the de nition. They should all make intuitive sense. Theorem 2.4. Let a;b 2Z with a jb. WebTwo useful properties of divisibility are (1) that if one positive integer divides a sec-ond positive integer, then the first is less than or equal to the second, and (2) that the only divisors of 1 are 1 and −1. Theorem 4.3.1 A Positive Divisor of a Positive Integer For all integers a and b,ifa and b are positive and a divides b, then a ≤ ...
Webdoable, it is also possible to prove the theorem for lower values of mand nallowing reducing n?. For example: Theorem 4.1. With n 6, the product of nconsecutive numbers strictly greater than nis divisible by at least two distinct primes strictly greater than n. Proof. Applying theorem 3.1 with E(1411) >2, that is n? = 1411 and r= 1 and checking all WebTheorem 3.9 If a b mod n, and c is a positive integer, then ca cb mod cn Proof: This is little more than a divisibility theorem. Since nj(b − a), we have cnjc(b− a) or cnj(cb −ca),andthisistheresult. The converse is also valid. Thus, if ca cb mod cn with c>0thena b mod n.
