d) m.m.c (35,10)

Answer 1

A) 
15,18/2
15,9/3
5,3/3
5,1/5
1,1          2x3x3x5= 90

B)
25,80/2
25,40/2
25,20/2
25,10/2
25,5/5
5,1/5
1,1             2x2x2x2x5x5= 400

C)
18,30/2
9,15/3
3,5/3
1,5/5
1,1         2x3x3x5= 90

D)
35,10/2
35,5/5
7,1/7
1,1          2x5x7= 70

Answer 2

Resposta

 a) m.m.c (15,18 )

15,18 / 3 
 5 , 6  / 2
 5 , 3 /  3
  5 ,1 /  5
   1 

mmc = 3 . 2 . 3 . 5 = 90

b) m.m.c (25,80)

25 , 80 / 2
25 , 40 / 2
25 , 20 / 2
25 , 10 / 2
25 , 5   / 5
  5 , 1  / 5
   1 

mmc = 2 . 2 . 2 . 2 . 5 . 5 = 400

c) m.m.c (18,30)

18 , 30 / 2
  9 , 15 / 3
   3 , 5 / 3
    1 ,5 / 5
        1

mmc = 2.3.3.5 = 90

d) m.m.c (35,10)

35 , 10  / 2
 35 , 5  / 5
  7 , 1  / 7
   1

mmc = 2 . 5 . 7 = 70
