Mam phi of 5 = 3 so prime no Ki law me phi of 5 = p -1 = 4 kaise Ho raha Hain??

[@sripad72]

If f: Zm --> Zn is onto homomorphism, then by first isomorphism theorem n must divide m.

[@currentaffairs2.06]

Mam if we have to write all the generator of Zn than all the generator of Zn are no which are co prime to n?

[@sadiquaquadir]

Ma'am,
But 1 is neither prime nor composite
So how can we count 1 ?

[@dr.upasanapahujataneja1707]

Gcd of any number with 1 is 1
