For two natural numbers m and n, the difference between their least common multiple and greatest common factor is recorded as m⊕n, namely: m⊕n=〔m,n〕-(m,n), such as 10⊕14=〔10, 14〕-(10, 14)=70-2=68, if 8⊕k=32, then k=how much.
对于两个自然数m、n，它们的最小公倍数与最大公因数的差记为m⊕n，即：m⊕n=〔m，n〕-(m，n)，如10⊕14=〔10，14〕-(10，14)=70-2=68，若8⊕k=32，则k=多少．
