Explanation: least common multiple is also known as lcm or lowest common multiple.
Explanation: coprime numbers have gcd 1. while lcm of coprime numbers is the product of those two coprime numbers.
Explanation: in terms of venn diagram, the lcm is given by the union of two sets. so a u b gives the lcm. while a κ΅ b gives the gcd.
Explanation: in terms of venn diagram, the lcm is given by the union of two sets. so a u b gives the lcm. so product of all the terms is 180.
Explanation: since the lcm function is commutative, so lcm (a, b) = lcm (b, a).
Explanation: coprime numbers have gcd 1
Explanation: since lcm function follows associativity, hence lcm (a, lcm (b, c) is equal to lcm (lcm (a, b), c).
Explanation: the lcm function is an associative function as lcm (a, lcm (b, c) is equal to lcm (lcm (a, b), c).
Explanation: since the lcm function follows absorption laws so lcm (a, gcd (a, b)) equal to a.
Explanation: the most efficient way of calculating the lcm of a given number is using euclid’s algorithm which computes the lcm in much lesser time compared to other algorithms.
