संख्या 72, 108 और 300 से विभाज्य होनी चाहिए।
प्रयुक्त अवधारणा:
इस प्रकार के प्रश्न के लिए, हम अभीष्ट संख्या को ज्ञात करने के लिए लघुत्तम समापवर्त्य विधि का उपयोग करते हैं।
गणना:
72 = 23 × 32
108 = 22 × 33
300 = 22 × 3 × 52
लघुत्तम समापवर्त्य = 23 × 33 × 52
⇒ 5400
अब संख्या, एक घन संख्या और 5400 की गुणज होनी चाहिए।
इसलिए,
5400 × 2 = 10800, जो एक घन संख्या नहीं है।
5400 × 3 = 16200, जो एक घन संख्या नहीं है।
5400 × 5 = 27000, जो एक घन संख्या है और सबसे छोटी है।
∴ वह सबसे छोटी घन संख्या, जो 72,108 और 300 से विभाज्य है, 27000 है।
