A
The highest common factor (HCF) of two numbers (or expression) is the largest number or expression which is a factor of both
B
The highest common factor (HCF) of two numbers (or expression) is the smallest number or expression which is a factor of both
C
The highest common factor (HCF) of two numbers (or expression) is the largest factor of either of the two numbers
D
The highest common factor (HCF) of two numbers (or expression) is the smallest factor of either of the two numbers
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.
