បង្ហាញថា
( l , m , n ) [ l m , m n , n l ] = l m n {\displaystyle (l,m,n)[lm,mn,nl]=lmn} ចំពោះចំនួនគត់រ៉ឺឡាទីបវិជ្ជមាន l , m , {\displaystyle l,m,} និង n {\displaystyle n} ។
តាង p {\displaystyle p} ជាចំនួនបឋមដែល
p d = l {\displaystyle p^{d}=l}
p e = m {\displaystyle p^{e}=m}
p f = n {\displaystyle p^{f}=n}
បើ
d ≤ e ≤ f {\displaystyle d\leq e\leq f}
d + e ≤ d + f ≤ e + f {\displaystyle d+e\leq d+f\leq e+f}
នោះ
( l , m , n ) = p d {\displaystyle (l,m,n)=p^{d}}
[ l m , m n , n l ] = p e + f {\displaystyle [lm,mn,nl]=p^{e+f}}
គេបាន
( l , m , n ) [ l m , m n , n l ] = p d + e + f {\displaystyle (l,m,n)[lm,mn,nl]=p^{d+e+f}}
តែ
l m n = p d + e + f {\displaystyle lmn=p^{d+e+f}}
មានន័យថា
( l , m , n ) [ l m , m n , n l ] = l m n {\displaystyle (l,m,n)[lm,mn,nl]=lmn}
