find the lcm of the following grops of number using the prime factorisation method to
18, 36,48​

Answer 1

Step-by-step explanation:

\begin{gathered}\rm \: = \: \dfrac{ - 58 + 63}{2}\\ \end{gathered}

=

2

−58+63

\begin{gathered}\rm \: = \: \dfrac{5}{2}\\ \end{gathered}

=

2

5

Hence,

\begin{gathered}\boxed{\tt{ \rm \:\dfrac{1}{2} \left | \begin{array}{ccc} - 4 &5&1 \\ 0&7&1 \\ 5& - 5&1\end{array}\right| + \dfrac{1}{2} \left | \begin{array}{ccc} - 4 &5&1 \\ - 4& - 2&1 \\ 5& - 5&1\end{array}\right| = \: \dfrac{5}{2}}}\\ \end{gathered}
