Answer 2

Given: The numbers $12,24$and$68$.

We have to find the HCF of the numbers $12,24$and$68$.

As we know that the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

We are solving in the following way:

The factors of $12$ are: $1, 2, 3, 4, 6, 12$

The factors of $24$ are: $1, 2, 3, 4, 6, 8, 12, 24$

The factors of $68$ are: $1, 2, 4, 17, 34, 68$

From the above, we can see that$4$ divides each of the integers.

$\therefore$ The HCF of the numbers $12,24$and$68$ will be: $4$

Hence, the HCF of the numbers $12,24$and$68$ will be$4$.
