ఇవ్వబడిన సంఖ్యను కారకం చేసి, ఆపై సాధ్యమయ్యే వర్గ కారకాలను పొందడానికి అదే సంఖ్యల జతలను చేయండి
లెక్కింపు:
⇒ 21600 = 2 2 × 2 2 × 2 × 3 2 × 3 × 5 2
ఖచ్చితమైన చతురస్రాలు 21600 కారకాలు
⇒ 1
⇒ 2 2 = 4,
⇒ 3 2 = 9,
⇒ 2 2 × 2 2 = 16
⇒ 5 2 = 25
⇒ 2 2 × 3 2 = 36
⇒ 2 2 × 5 2 = 100
⇒ 2 2 × 2 2 × 3 2 = 144
⇒ 3 2 × 5 2 = 225
⇒ 2 2 × 2 2 × 5 2 = 400
⇒ 3 2 × 5 2 × 2 2 = 900
⇒ 3 2 × 5 2 × 2 4 = 3600
ఖచ్చితమైన చతురస్రం = 12 ఉన్న 21600 కారకాల సంఖ్య
∴ 21600 ఖచ్చితమైన చతురస్రాల సంఖ్య యొక్క కారకాలు 12
