Least common multiple (lcm)

lcm(Integer, ..., Integer)

lcm(List)

lcm(Vector)

lcm(Fraction, Fraction)

Given a set of integers $a_1$, ...,$a_n$ , returns the least number that is a multiple of $a_1$, ...,$a_n$ simultaneously.

Given a list of integers $\{a_1,...,a_n\}$ , returns the least number that is a multiple of $a_1$, ...,$a_n$ simultaneously.

Given a vector of integers $[a_1,...,a_n]$ , returns the least number that is a multiple of $a_1$, ...,$a_n$ simultaneously.

Given two fractions $\frac{a}{b}$ and $\frac{c}{d}$, returns its least common multiple defined as $lcm\left(\frac{a}{b},\frac{c}{d}\right)=\frac{lcm(a,c)}{gcd(b,d)}$
