最佳解答:

1.2007/72=27.875, so 72*28>2007, n=28 2.「設正整數x除以7得5」, 是得餘數五吧？如果是, 那, R7( xy )=( 5*4 )=( 20 )=6 3. 2a+1｜2a+1, 2a+1｜3a+7 2a+1｜6a-6a+14-3, 2a+1｜11 2a+1=±1, ±11 a為正整數, 所以a=6 4. 最接近５０３的完全平方數為４８４, 也就是２２的平方, 所以只要檢察２～１９的質數是否為５０３的因數就可以了, ６６７也是一樣, ５０３為質數, ６６７=２３×２９ 5. p=(a2+7a+13)(a2-8a+13), 所以(a2+7a+13)或(a2-8a+13)其中一個為±1, 若(a2+7a+13)為±1, 則, a為負數, 不合若(a2-8a+13)為±1, 則, a為6或2, 帶進(a2+7a+13), 答案為２ 6. 3a79b為４和１１的倍數, 所以b為2或6（因為４）至於１１的部份, 分為3a792, 3a796, 第一組帶進去, 12=9+a, a=3 第二組帶進去, 16=9+a, a=7 所以這個五位數可能為33792和37796 7. ( 1050,650 )=50ｃｍ 21*13=273塊( 因為1050/50=21, 650/50=13 ) 8. 用輾轉相除法, ｜1653｜2001｜1 4｜1392｜1653｜￣￣￣￣￣￣￣｜ 261｜ 348｜1 3｜ 261｜ 261｜￣￣￣￣￣￣￣｜0 ｜ 87｜ ( 1653,2001 )=87 1653*2001=87*[ 1653,2001 ], [ 1653,2001 ]=37950 9. 用輾轉相除法, ｜ａ｜ｂ｜ｑ2 ｑ1｜ｂｑ1｜4092ｑ2｜￣￣￣￣￣￣￣￣￣｜4092 ｜ 588 ｜ｑ3｜588q3｜ 576 ｜16 ￣￣￣￣￣￣￣￣￣｜３６｜ 12 ｜３｜３６￣￣￣￣０（ａ,ｂ）＝３６ 10.我不會算耶...不好意思, 但你確定是( a,b )?不是[ a,b ]?
