### Solution:

Concept- HCF: HCF means highest common factor, the divisors of two numbers and then we find the largest divisor to find the highest common factor
HCF is basically the highest common divisor of the  numbers,
Suppose, we have to find the highest common divisor of two numbers 25 and 35,
The factors of 25,
The factors of 35,
Then the highest common factor of 25 and 35 is 5
Hence, the correct option is 1.
