Nuprl Lemma : coprime_iff_ndivides
∀a,p:ℤ.  (prime(p) 
⇒ (CoPrime(p,a) 
⇐⇒ ¬(p | a)))
Proof
Definitions occuring in Statement : 
prime: prime(a)
, 
coprime: CoPrime(a,b)
, 
divides: b | a
, 
all: ∀x:A. B[x]
, 
iff: P 
⇐⇒ Q
, 
not: ¬A
, 
implies: P 
⇒ Q
, 
int: ℤ
Definitions unfolded in proof : 
rev_implies: P 
⇐ Q
, 
prop: ℙ
, 
uall: ∀[x:A]. B[x]
, 
member: t ∈ T
, 
false: False
, 
not: ¬A
, 
and: P ∧ Q
, 
iff: P 
⇐⇒ Q
, 
implies: P 
⇒ Q
, 
all: ∀x:A. B[x]
, 
prime: prime(a)
