Question

if a and b are two positive integers
where a is greater than zero and b is a factor of a then find the hcf of a and b
​

Answer 1

ANSWER

HCF is a

a and b are two naturals

where b is a factor of a

To find : the hcf of a and b

As b is a factor of a we can let $b=ak$

where k is a natural

As hcf of k and 1 is always 1

the hcf of a and ak is a

We conclude that

HCF is a
