!! REPEDE VĂ ROGG!! ​

Answer 1

a) c.m.m.m.c

[ 2, 4, 6, 8 ]= 2³ • 3 = 8 • 3 = 24

2= 2¹

4= 2²

6=2 • 3

8= 2³

b) c.m.m.m.c

[ 10, 15, 30, 60 ]= 2²• 3 • 5 = 4•3•5= 60

10= 2 • 5

15= 3 • 5

30= 2 • 3 • 5

60= 2² • 3 • 5

c) c.m.m.m.c

[ 20, 25, 45, 70 ]= 2²• 3²• 5²• 7= 6300

20= 2² • 5

25= 5²

45= 3² • 5

70= 2 • 5 • 7

d) c.m.m.m.c

[ 11, 33, 66, 99 ]= 2•3²•11= 198

11= 11

33= 3• 11

66= 2 • 3 • 11

99= 3²• 11
