cho a / b = 85 / 153 , UCLN ( a , b ) = 15 . tim a , b
biet UCLN(a,b)=15. tim UCLN(A+B,a-b)
cho a/b=15/35,biet UCLN(a,b).BCNN(a,b)=3549
tim (a,b)
tim a,b
a- b = 90 va UCLN a,b = 15
BCNN(a,b)=300
UCLN(a,b)=15
Va a+15=b
tim a b
tim hai so tu nhien a va b ; biet a + b = 180 va UCLN ( a , b ) = 15
tim cac STN a va b biet
a*b=1350 va UCLN(a;b) =15
tim BCNN cua a,b =300
UCLN cua a va b =15
a, ab = 360 va BCNN[ a;b] = 60
b, UCLN[a:;b] =12 va BCNN[a;b] = 72
c, UCLN[a;b] = 15 va BCNN[a;b]=2100.UCLN[a;b]
