Question

find the hcf of 55,51,65

​

Answer 1

Answer

the answer is 1 because 51 is only divisible by 3 and 1. 55 and 51 has only 5 and 1 in common. so it makes 1 common in all the three no.s

Answer 2

Answer:

The HCF of 55, 51, and 65 is 1.

Step-by-step explanation:

Given: The numbers are 55, 51, and 65.

We have to find the HCF of the above numbers.

• As we know, the HCF (Highest Common Factor) of two or more numbers is the highest number among all the common factors of the given numbers.
• HCF is also known as the greatest common factor.

We are solving in the following way:

We have,

The numbers are 55, 51, and 65.

First, we will find the factors of the above numbers.

The factors of 51 are: $1, 3, 17, 5$

The factors of 55 are: $1, 5, 11, 55$

The factors of 65 are: $1, 5, 13, 65$

From the above, we can see that 1 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 1.
