Question

The HCF of 33, 55 and 110 is?

Answer 1

Solution :-

HCF of 33, 55 and 110

Prime Factors of 33 = 3 × 11

Prime Factors of 55 = 5 × 11

Prime Factors of 110 = 2 × 5 × 11

Common factor = 11

So, HCF of 33, 55 and 110 is 11

Answer.

Answer 2

11 is the HCF of 33, 55 and 110.

Given:

33, 55 and 110

To find:

HCF of 33, 55 and 110

Solution:

Let us find the factors of 33, 55 and 110

To find the factors of 33, we use the simple division with lowest prime factor we get for 33;

$33=3 \times 11$

Similarly, we find the HCF of the other two vales as well that will be

$\begin{array}{l}{55=5 \times 11} \\ {110=11 \times 10}\end{array}$

Thereby, each of them has 11 in common so we can see that the value of HCF of 33, 55, 110 is 11.
