Question:

Find the LCM of 6, 8 and 12.

Answer:

 \fbox{\bold{LCM(6,8,12) = 24}}

Step-by-step explanation:

The prime factorisation of 6 is,

 \begin{array}{r | l} 2 & 6 \\ \cline{1-2} 3 & 3 \\ \cline{1-2} & 1 \end{array}

The prime factorisation of 6 =  2 \times 3

The prime factorisation of 8,

 \begin{array}{r | l} 2 & 8 \\ \cline{1-2} 2 & 4 \\ \cline{1-2} 2 & 2 \\ \cline{1-2} & 1 \end{array}

The prime factorisation of 8 =  2 \times 2 \times 2

The prime factorisation of 12 is,

 \begin{array}{r | l} 2 & 12 \\ \cline{1-2} 2 & 6 \\ \cline{1-2} 3 & 3 \\ \cline{1-2} & 1 \end{array}

The prime factorisation of 12 =  2 \times 2 \times 3

Factors(6) =  2 \times 3

Factors(8) =  2 \times 2 \times 2

Factors(12) =  2 \times 2 \times 3

Now LCM of 6, 8 and 12,

LCM(6,8,12) =  2 \times 2 \times 2 \times 3

 \fbox{\bold{LCM(6,8,12) = 24}}
