Question 464643

Least Common Multiple or {{{LCM}}}:

The smallest (non-zero) number that is a multiple of two or more numbers.


Let's use prime factorization.

{{{21a^2b^6,=3*7*a*a*b*b*b*b*b*b}}}

{{{3a^4b^8  =3*a*a*a*a*b*b*b*b*b*b*b*b}}}

{{{14a^5b^8 =2*7*a*a*a*a*a*b*b*b*b*b*b*b*b}}}


Prime factors are {{{2}}}, {{{3}}}, {{{7}]] and {{{a*a*b*b*b*b*b*b}}}.


 {{{LCM=2*3*7 * a*a*b*b*b*b*b*b}}}

 {{{LCM=42* a^2*b^6}}}
