calculati c.m.m.d.c(cel mai mare divizor comun):b)90 si 168. c)100,280 si 980. d)875 si 550. e)50,75 si 120. g)112,28 si 98. dau coroana

Answer 1

b) 90=2•3^2•5
168=2^3•3•7
(90,168)=2•3=6
c) 100=2^2•5^2
280=2^3•5•7
980=2^2•5•7^2
(100,280,980=2^2•5=20
d) 875=5^2•7^2
550=2•5^2•11
(875,550)=5^2=25
e) 50=2•5^2
75=3•5^2
120=2^3•3•5
(50,75,120)=5
g) 112=2^4•7
28=2^2•7
98=2•7^2
(112,28,98)=2•7=14
