Question

The Length breadth and height of a room are 8 metre 25 CM, 6 may 75 cm and 450 CM respectively . Find the longest state which can measure the 3 dimensions of the room exactly.

Answer 1

L=8m 25cm=825cm
B=6m75cm=675cm
H=450cm=450cm

HCF OF 825cm ,675cm, 450cm

825= 3×5×5×11
675=3×3×5×5
450=2×3×3×5×5
We have to find the HCF to find out the longest tape which can measure the dimension of the room exactly.
hence HCF is =5×5×3=75cm
