Answer 2

In context to question asked,

We have to determine the HCF of given number.

As per question,

We have, numbers - 18, 24, 72

As we know that,

HCF of two or more number are that particular number which is highest number which is also a common factor of all the given number.

So, for determining the HCF of given number we will use prime factorization method.

Hence, Prime factorization of given number will be,

$18 = 3\times 2 \times 3\\24 = 2\times 2 \times 2 \times 3\\72 = 2\times 3 \times 2 \times 2 \times 3\\=>HCF = 3\times 2 = 6 \:(Common \:number\:among\:all)$

Hence, HCF of the given number will be 6
