Question

find HCF of the following given below K, 2K, 3K, 4K, and 5K, where K is any positive integer.

Answer 1

hcf is k because all are divided by k and k is the smallest number divided by k, 2k, 3k, 4k,5k.....

therefor "k" is the hcf.



if k=1
then numbers =1,2,3,4,5
hcf=k=1

if k =2
numbers=2,4,6,8,10
hcf=k=2

Answer 2

the answer is k the hcf
