Question

define LCM...........​

Answer 1

$\large\underlined{\mathfrak{LCM => Least \ Common \ Factor}}$

=>The Least Common Multiple (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers.

=> For instance, the LCM of 16 and 20 is 80; 80 is the smallest number that is both a multiple of 16 and a multiple of 20.

=>You can find the LCM of two or more numbers through various methods.

LCM:-

In arithmetic and number theory, the least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, usually denoted by lcm(a, b), is the smallest positive integer that is divisible by both a and b.Since division of integers by zero is undefined, this definition has meaning only if a and b are both different from zero. However, some authors define lcm(a,0) as 0 for all a, which is the result of taking the lcm to be the least upper bound in the lattice of divisibility.

The lcm is the "lowest common denominator" (lcd) that can be used before fractions can be added, subtracted or compared. The lcm of more than two integers is also well-defined: it is the smallest positive integer that is divisible by each of them.
