Tim 2 so a va b biet UCLN(a,b)=12;BCNN(a,b)=72

tim hai so tu nhien a va b biet :BCNN[A,B]=180;ƯCLN[a,b]=12

Biet rang : BCNN(a,b).UCLN(a,b)

a, BCNN cua hai so la 600, UCLN cua chung nho hon 10 lan BCNN. So thu 1 la 120, tim so thu 2.

b, UCLN cua hai so la 12, BCNN cua chung lon gap 6 lan UCLN . So t 1 la 24, tim so t 2

c, Tong cua hai so bang 60, tong giua UCLN va BCNN cua chung la 84. Tim hai so do.

biet BCNN[A,B]=60

A nhan B =1800

tim a va b

giúp tôi với tôi vội lắm rồi

biet rang BCNN(a,b).UCLN(a,b)=a.b 

a, tong cua hai so bang 60,tong giua UCLN va BCNN cua chung la 84 tim hai so do

           BCNN[a,b] = 240 va UCLN[a,b] = 12 

Tim 2 stn a va b biet UCLN(a,b)=12, BCNN(a,b)=756

HELP ME

Tim so tu nhien b biet 10<b<20 va BCNN(15,b)=60

        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]
