Question

The dimensions of room are 8m , 12 m and 10m. Find the lengths of the measuring tape which can measure it in equal parts.

  1. 2m
  2. 4m
  3. 6m
  4. 8m

The correct answer is: 2m


    To measure the lengths of the room in equal parts we need to find GCF (8,12,10)
    GCF (8,12,10) = 2
