Question

The HCF of 150 and k is 30. The value of k can be equal to

Answer 1

Given : The HCF of 150 and k is 30.

To find :   The possible value of k

Solution:

HCF  of  150   &  K   is   30

HCF - highest Common Factor

150  = 30 * 5

K   = 30 * n     ( where n  is co prime with 5   & n ∈ N ) ( means n is not a multiper of 5)

as HCF = 30

K can be  30 , 60 , 90 , 120 , 180 , 210 ,  240 , 270 , 330  

and so on

So Basically K   = 30 * n         ( where n  is co prime with 5   & n ∈ N )
