প্রদত্ত:

তিনটি সংখ্যার অনুপাত 2 : 3 : 5

তিনটি সংখ্যার  ল.সা.গু = 90

গণনা:

ধরা যাক, সংখ্যা তিনটি 2x, 3x এবং 5x.

(2x, 3x এবং 5x) এর  ল.সা.গু = 2 × 3 × 5 × (x)

⇒ 30x

প্রশ্ন অনুসারে, 30x = 90

⇒ x = 90/30

⇒ x = 3

সুতরাং, সংখ্যাগুলি হল 6, 9, 15

এখন,

6 = 2 × 3

9 = 32

15 = 3 × 5 

তাহলে, তাদের গ.সা.গু = 3

∴ তিনটি সংখ্যার গ.সা.গু 3.
