✔ 最佳答案
先搵哂所有兩位因數,,
乘左出黎係=1653,,
再睇睇佢地邊PAIR係4個數都唔同囉!
至於咁煩囂既工作,,
就只可以由D叻人自己做,,
我就好STUD,,
所以幫你唔到勒!

2006-12-25 16:44:49 補充:
算啦,,幫你計埋勒!佢既個位數係3,,個位數相乘既個位係3,,就只係得3X1or7同埋7x9所以個B同埋D只會係3,1,7,9就由11TRY先,,TRY到19先得既..19X87,,下一組就係19-87既兩個數,,即係29X57,,所有答案都係得2組炸,,AB=19,,87,,29,,57CD=19,,87,,29,,57
參考: NO啦!小學教我奧數D老師囉......
