Answer» Take H.C.F. of 156, 208 and 260. => HCF of 156 and 208 P.F. of 156 = 2×2×3×13P.F. of 208 = 2×2×2×2×13Therefore, H.C.F. of 156 and 208 = 2×2×13 = 52 => Now , H.C.F. of 52 and 260 P.F. of 52 = 2×2×13P.F. of 260 = 2×2×5×13H.C.F. = 2×2×13 = 52 ●Max. number of students per bus = 52 ●Total number of students = 156+208+260 = 624 students. ●No. of buses = 624/52 = 12 buses. |
