Answer 1

Răspuns:

a. (2,4)

4=2²

cmmdc (2,4) =2

b. (4,6)

4=2²

6=2x3

cmmdc (4,6)=2

c. (5,10)

4=2²

6=2x3

cmmdc (5,10)=2

d. 9=3²

15=3x5

cmmdc (9,15)=3

e. (3,6,9)

3=3

6=2x3

9=3²

cmmdc (3,6,9)=3

f. (2,4,6,10)

2=2

4=2²

6=2x3

10=2x5

cmmdc (2,4,6,10)=2

g. (10,20,30,50)

10=2x5

20=2²x5

30=2x3x5

50=2x5²

cmmdc (10,20,30,50)=2x5=10

h. (2,4,8)

2=2

4=2²

8=2³

cmmdc (2,4,8) =2

i. (4,18,32)

4=2²

18=2x3²

32=2⁵

cmmdc (4,18,32) =2

j. (5,15,30,45)

5=5

15=3x5

30=2x3x5

45=3²x5

cmmdc (5,15,30,45)=5

k. (12,24,36)

12=2²x3

24=2³x3

36=2²x3²

cmmdc (12,24,36)=2²x3=12

l. (4,15,60)

4=2²

15=3x5

60=2²x3x5

cmmdc (4,15,60) =1
