⇒134×217×445⇒74×157×245⇒77×155×244⇒1×3×6⇒18.\Rightarrow 1\dfrac{3}{4} \times 2\dfrac{1}{7} \times 4\dfrac{4}{5}\\[1em] \Rightarrow \dfrac{7}{4} \times \dfrac{15}{7} \times \dfrac{24}{5}\\[1em] \Rightarrow \dfrac{7}{7} \times \dfrac{15}{5} \times \dfrac{24}{4} \\[1em] \Rightarrow 1 \times 3\times 6 \\[1em] \Rightarrow 18.⇒143×271×454⇒47×715×524⇒77×515×424⇒1×3×6⇒18.
Hence, 134×217×445=181\dfrac{3}{4} \times 2\dfrac{1}{7} \times 4\dfrac{4}{5} = 18143×271×454=18.
