greatest measuring lengths would be HCF of all given nos
7m=700cm, 3m=300cm, 85cm , 12m=1200cm, 95cm
700=2×2×5×5×7
300=2×2×3×5×5
85=5×17
1200=2×2×2×2×3×5×5
95 = 5×19
HCF =5
THE greatest possible length to measure exactly all the given lengths is 5cm
7m=700cm, 3m=300cm, 85cm , 12m=1200cm, 95cm
700=2×2×5×5×7
300=2×2×3×5×5
85=5×17
1200=2×2×2×2×3×5×5
95 = 5×19
HCF =5
THE greatest possible length to measure exactly all the given lengths is 5cm
