Question

What is the HCF of 2.04 ; 0.24 ; 0.8

Answer 1

HCF stands for Highest Common Factor. It is the highest number which can divide each of the given numbers completely i.e. leaving no remainder.

We can write the given numbers as follows:
204/100 , 24/100 and 8/10

Multiplying each number by 100,
204 , 24 and 80

Now calculating the HCF,

204 = 2 * 2 * 3 * 17
24 = 2 * 2 * 2 * 3
80 = 2 * 2 * 2 * 2 * 5

Taking out the common factors,

HCF = 2 * 2

Hence,

Highest Common Factor of 204 , 24 and 80 = 4

Now dividing the HCF by 100 to get the required answer = 0.04

Therefore,

Highest Common Factor of 2.04, 0.24 and 0.8 = 0.04
