What 11 concepts are covered in the Greatest Common Factor and Least Common Multiple Calculator?

division: separate a number into parts
division: separate a number into parts
factor: a divisor of an integer n, also called a factor of n, is an integer m that may be multiplied by some integer to produce n.
greatest common factor: largest positive integer dividing a set of integers
greatest common factor and least common multiple
least common multiple: Given 2 numbers a and b, the least common multiple LCM is the smallest positive integer that is divisible by both. It is commonly denoted as LCM(a, b)
minimum: the least or lowest amount possible or attained
multiple: the product of any quantity and an integer
number: an arithmetical value, expressed by a word, symbol, or figure, representing a particular quantity and used in counting and making calculations and for showing order in a series or for identification. A quantity or amount.
prime factorization: the prime numbers that divide that integer exactly
remainder: The portion of a division operation leftover after dividing two integers
