公因數(shù)

只有1

的兩個(gè)數(shù)，叫做互質(zhì)數(shù)．相鄰的兩個(gè)非0整數(shù)是互質(zhì)數(shù)；兩個(gè)不同的質(zhì)數(shù)是互質(zhì)數(shù)；2和任何一個(gè)奇數(shù)是互質(zhì)數(shù)；1和任意一個(gè)非0偶數(shù)是互質(zhì)數(shù)．

Answer 1

分析：根據(jù)互質(zhì)數(shù)的意義，公因數(shù)只有1的兩個(gè)數(shù)叫做互質(zhì)數(shù)．據(jù)此解答．

解答：解：公因數(shù)只有1的兩個(gè)數(shù)叫做互質(zhì)數(shù)．相鄰的兩個(gè)非0整數(shù)是互質(zhì)數(shù)；兩個(gè)不同的質(zhì)數(shù)是互質(zhì)數(shù)；2和任何一個(gè)奇數(shù)是互質(zhì)數(shù)；1和任意一個(gè)非0偶數(shù)是互質(zhì)數(shù)．
故答案為：只有1．

點(diǎn)評(píng)：此題考查的目的是理解掌握互質(zhì)數(shù)的概念及意義．
