整數(shù)a除整數(shù)b,商是18,a與b的最大公約數(shù)是________,最小公約數(shù)是________.
a b
分析:根據(jù)“整數(shù)a除整數(shù)b,商是18”,可知b是a的倍數(shù),當兩個數(shù)有倍數(shù)關系時,它們的最大公約數(shù)為較小數(shù),最小公倍數(shù)為較大數(shù);由此解答問題即可.
解答:因為整數(shù)a除整數(shù)b,商是18,
可知b是a的倍數(shù),a是b的因數(shù),
所以a和b的最大公約數(shù)是a,最小公倍數(shù)是b.
故答案為:a,b.
點評:此題主要考查求兩個數(shù)為倍數(shù)關系時的最大公因數(shù)和最小公倍數(shù):兩個數(shù)為倍數(shù)關系,最大公約數(shù)為較小的數(shù),最小公倍數(shù)為較大數(shù).本題注意除和除以的區(qū)別.
