Length of copper wire = 72 inches
length of steel wire = 42 inches
The largest piece of wire that can be cut from the wires so that each pieces is same is the HCF of 72 and 42.
72 = 2×2×2×3×3
42 = 2×3×7
HCF = 2×3 = 6 inches.
the largest pieces of wire he can cut so that each pieces is the same is 6 inches.
