ती संख्या 72, 108 आणि 300 ने विभाज्य असली पाहिजे.
वापरलेली संकल्पना:
सदर प्रकारच्या प्रश्नासाठी, आपण आवश्यक संख्या शोधण्यासाठी लसाविचा वापर करतो
गणना:
72 = 23 × 32
108 = 22 × 33
300 = 22 × 3 × 52
लसावि = 23 × 33 × 52
⇒ 5400
आता ती संख्या एक घन संख्या आणि 5400 च्या पटीत असली पाहिजे.
अशाप्रकारे,
5400 × 2 = 10800 ही एक घन संख्या नाही.
5400 × 3 = 16200 ही एक घन संख्या नाही.
5400 × 5 = 27000 ही एक घन संख्या असून ती सर्वात लहान आहे.
∴ 72, 108 आणि 300 ने विभाज्य असलेली सर्वात लहान घन संख्या 27000 आहे.
