Home » Aptitude » LCM and HCF » Question

Two pipes of length 1.5 m and 1.2 m are to be cut into equal pieces without leaving any extra length of pipes. The greatest length of the pipe pieces of same size which can be cut from these two lengths will be

1. 0.13 metre
2. 0.4 metre
3. 0.3 metre
4. 0.41 metre

Correct Option: C

Maximum length of each piece = HCF of 1.5 metre and 1.2 metre
First of all we find HCF of 1.5 metre and 1.2 metre

∴ HCF of 1.5 and 1.2 metre = 0.3 metre
Required Maximum length of each piece = 0.3 metre
