Detailed Solution
Download Solution PDFGiven:
Length of timber1 = 143 m
Length of timber2 = 78 m
Length of timber3 = 117 m
Calculation:
Greatest possible length of each plank = HCF of 143, 78 and 117
143 = 13 × 11
78 = 13 × 2 × 3
117 = 13 × 3 × 3
HCF is 13
∴ Greatest possible length of each plank is 13 m.
