Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
3 सलग चार विभाजकांची बेरीज = 78
गणना:
समजा 3 चा पहिला विभाजक = 3a आहे
त्याचप्रमाणे, 3 चा दुसरा विभाजक be = 3(a + 1)
⇒ 3 चा तिसरा विभाजक = 3(a + 2)
⇒ 3 चा चौथा विभाजक be = 3(a + 3)
3a +3(a + 1) + 3(a + 2) + 3(a + 3) = 78
⇒ 3a + 3a + 3 + 3a + 6 + 3a + 9 = 78
⇒ 12a + 18 = 78
⇒ 12a = 78 - 18 = 60
⇒ a = 60/12 = 5
∴ 3 चा सर्वात मोठा विभाजक = 3(a + 3) = 3 × (5 + 3) = 24
Shortcut Trick
गणना:
3 च्या सलग 4 विभाजकांची सरासरी = 78/4 = 19.5
तर, संख्या 18 आणि 21 असावी.
तर, मालिका असेल
15, 18, 21, 24
∴ सर्वात मोठा विभाजक 24 आहे.
