Answer 2

Answer:

HCF of 28, 35, and 49 is 7.

Solution:

28, 35, 49 are the data that is given.

We need to find the HCF of the data.

HCF is abbreviated as the highest common factor.

To find HCF we need to find common multiple factor.

First consider 28 = 2 x 2 x 7 is multiple of 28.

The multiple of 35 is 5 x 7 and the last number is 49 = 7 x 7 is the multiple of 49.

Therefore, the common factor is 7.

Hence the HCF of a given number is 7.
