ఇవ్వబడినవి:

ఐదు అంకెల సంఖ్య 247xy 3, 7 మరియు 11 ద్వారా భాగించబడినట్లయితే

లెక్కింపు:

3, 7, 11 యొక్క క.సా.గు 231

ప్రశ్న ప్రకారం

247xy యొక్క అతిపెద్ద సాధ్యం విలువ 24799

మనం 24799ని 231తో భాగిస్తే మనకు 82 మిగిలి ఉంటుంది

సంఖ్య = 24799 82

⇒ 24717

ఇప్పుడు x = 1 మరియు y = 7

(2y 8x) = (2 × 7 – 8 × 1)

⇒ (14 - 8)

⇒ 6

∴ అవసరమైన విలువ 6
