Answer 2

Hello !!

This method below is prime factorization.

$\begin{array}{r|l}72,120,90&2\\36,60,45&2\\18,30,45&2\\9,15,45&3\\3,5,15&3\\1,5,5&5\\1,1,1\end{array}$

Now, you calculate the least common multiple.

LCM = 2 × 2 × 2 × 3 × 3 × 5

LCM = 8 × 9 × 5

LCM = 72 × 5

LCM = 360

Final result : the least common multiple is 360.
