Question

) There are 4 poles measuring 105 cm, 120 cm, 125 cm and 140 cm. If they have to be arranged into pieces of equal length, what is the maximum length they have to be cut into?

Answer 1

This is a question about HCF. You have to cut these rods into pieces ,separately such that each piece is equal in length and you have to find the maximum possible length of these pieces .
Just use the HCF of 105,120,125,140
the HCF is 5
Therfore the maximum length they can be cut into is 5cm

Answer 2

take out teh HCF of 105 , 120 , 135 , 140 . the HCF is 5 . so they have to cut into 5 peices .
