The greatest possible length which can be used to measure exactly the length 5 m 25 cm,7 m 35 cm and 4 m 90 cm is

Correct option is C

Given:

Length given are 5m 25cm, 7m 35cm and 4m 90cm

Formula Used:

HCF and LCM

1m = 100cm

Solution:

5m 25cm = 525cm

7m 35cm =735cm

4m 90cm = 490cm

HCF of 525cm,735cm and 490m

525 = $$3 \times 5^2 \times 7$$​​

735 = $$3 \times 5^2 \times 7$$​​

490 = $$2 \times 5 \times 7^2$$​​

HCF = $$5 \times 7 = 35cm$$​​
