Vi UCLN(a,b).BCNN(a,b) =a.b
Do do UCLN(a,b)= 360:60=6
Dat a= 6x, b= 6y voi UCLN(x,y) = 1
Ta co 6x.6y = 360
x.y= 360:36 10
Ta xet
. Neu x= 1 thi y = 10
. Neu x = 2 thi y = 5
. Neu x = 10 thi y = 1
. Neu x = 5 thi y = 2
Do do ta co :
a = 6.1 = 6, b = 6.10 = 60
a = 6.2 = 12, b = 6.5 = 30
a = 6.10 = 60, b = 6.1 =6
a = 6.5 = 30, b = 6.2 =12

a+9 chia hết cho 17 ; 25
a nhỏ nhất

=> a =425 - 9 =416
a = 416
