Содержание слайда: A prime number - it is a natural number greater than one that has exactly two positive divisors: 1 and itself. The study deals with the properties of prime numbers theory of numbers. A prime number is an integer p > 1 such that it cannot be written as p = ab with a, b > 1.

A prime number is an integer p > 1 such that it cannot be written as p = ab with a, b > 1. Example: 7 is prime because the only numbers that will divide into it evenly are 1 and 7.

The algorithm is named for the Greek mathematician Euclid, who first described it in the VII and X book "Principia." In the simplest case, Euclid's algorithm is applied to a pair of positive integers, and generates a new pair consisting of a smaller number, and the difference between larger and smaller integer. The process is repeated until the numbers become equal. The obtained number is the greatest common divisor of the original pair.

Replace (a, b) with (r, a) and go to Step 3

Содержание слайда: In principle, Euclid's algorithm will do, and whole numbers, such as the length of the segment. Then it allows you to find the greatest common measure of two segments, that is, the largest of the intervals entirely fit into both data if such a measure exists: it exists, if the segments are commensurable, ie the ratio of their lengths is a rational number.
