C++ algorithm to calculate least common multiple for multiple numbers

Question

Is there a C++ algorithm to calculate the least common multiple for multiple numbers, like lcm(3,6,12) or lcm(5,7,9,12)?

Answer 1

boost provides functions for calculation lcm of 2 numbers (see here)

Then using the fact that

lcm(a,b,c) = lcm(lcm(a,b),c)

You can easily calculate lcm for multiple numbers as well
