Answer :
[tex]LCM\ is\ the\ least\ common\ number\ that\ is\ multiply\ of\ both:\\\\
Factors\ of\ 13\\ 13:13\\\\
Factors\ of\ 26:\\ 26:2\\ 13:13\\\\
LCM(13,26)=2*13=26\\\\
\textbf{LCM(13,26)=26}
[/tex]
The lest common multiple is 26. If you do multiples of each number
13:13,26
26: 26
Both of their lest common multiples would be 26
13:13,26
26: 26
Both of their lest common multiples would be 26
