LCM and HCF Practice Test 4

Question : 30 of 40

Marks: +1, -0

Find the HCF of 6.3, 1.33 and 56.7.

Solution:

The HCF of 6.3, 1.33 and 56.7 = HCF of

(63/10,133/100,567/10)

HCF of

(63/10,133/100,567/10)

={\HCF\of(63,133,567)}/{\LCM\of (10,100,10)}

63 = 7× 3^2

133= 7 ×19

567= 7 ×3 ^4

So, HCF of 63, 133 and 567 is 7.

=7/100=0.07
