The relation ''is a factor of'' on the set N of all natural number is not

Show that the relation ‘is a factor of’ on the set N of all natural numbers is reflexive and transitive but not symmetric.

Check the relation is a factor of on the set of natural numbers N for reflexivity symmetry and transitivity.

The relation R on the set N of all natural numbers defined by (x ,\ y) in RhArrx divides y , for all x ,\ y in N is transitive.

The relation R on the set N of all natural numbers defined by (x,y)in R hArr x divides y, for all x,y in N is transitive.

The relation R is defined on the set of natural numbers N as x is a factor of y where x, y in N. Then R is -

The relation '>' in the set of N (Nature=al number)

Prove that 7 is a factor of 2^(3n)-1 for all natural numbers n.

Show that the relation R in the set of all natural number, N defined by is an R = {(a , b) : |a - b| "is even"} in an equivalence relation.
