Question

The lengths of three wires were 30 m, 36 m and 84 m. Pieces of wire of equal length were cut

from the three wires. Calculate the least number of pieces obtained.​

Answer 1

Answer: HCF of 30,36 and 84 is 6

so, by cutting equal lenghts of wire by 6 metres we get 30/6,36/6,84/6=5,6 and 14.

the least number of pieces obtained is 25 by adding 5, 6 and 14.
