Length of four pipes are 28 m, 42m , 84m and 133m respectively and to be cut into pieces of equal length, find the maximum possible length of each piece.
To find the maximum possible length of each piece, we need to find out the HCF of 28 m, 42m, 84m and 133m. HCF of 28, 42, 84 and 133 = 7 Maximum possible length of each piece = 7 meter.
