Question

Two ropes 12 m and 18 m long are to be cut into small pieces of equal lengths. What will be the greatest length of each piece ?

Answer 1

HCF of 12,18=6

Greatest length=6cm

Answer 2

Answer:

12=2×2×3

18=2×3×3

Maximum length of the piece that has to be cut=H.C.F of 12m and 18m

Now HCF of 12 and 18 is 6

∴ Required length=6m
