The least common multiple (lcm) of two or more integers is the smallest positive integer that is divisible by all of them. Learn how to compute lcm using prime factorization, greatest common divisor, or other methods, and see applications in fractions, gears, and planetary alignment.
The greatest common divisor (GCD) of two or more integers is the largest positive integer that divides each of them. Learn the definition, examples, applications, and methods of computing GCD, such as Euclid's algorithm.
Learn how to compute the greatest common divisor (GCD) of two integers using Euclid's method, which is based on repeated subtraction or division. Find out the applications, history, and generalizations of this algorithm in number theory and cryptography.
Learn the definition, applications and algorithms of the longest common substring problem in computer science. Compare the time and space complexity of suffix tree and dynamic programming methods.
A fraction that is reducible can be reduced by dividing both the numerator and denominator by a common factor. It can be fully reduced to lowest terms if both are divided by their greatest common divisor. [5] In order to find the greatest common divisor, the Euclidean algorithm or prime factorization can be used. The Euclidean algorithm is ...
The lowest common denominator (LCD) is the lowest common multiple of the denominators of a set of fractions. It simplifies adding, subtracting, and comparing fractions. Learn how to calculate the LCD and its practical uses.
This web page shows the prime factorization of the natural numbers from 1 to 1000. It does not answer the query for the smallest number with 4 prime factors, but it provides some properties and definitions related to prime numbers and their factors.
