We do prime factorization for $$25$$ and $$125$$ first. $$25={{5}^{2}}$$ and $$125={{5}^{3}}$$. We have three $$5$$'s, thus the least common multiple for $$25$$ and $$125$$ is $$125$$. We choose $$\text{B}$$． 
Which of the followings is the least common multiple for $$25$$ and $$125$$? 
A. $$25$$ 
B. $$125$$ 
C. $$130$$ 
D. $$600$$
