Soluções para a tarefa
Oi...
O MMC e MDC de:
a)
45, 168/2
45, 84/2
45, 42/2
45, 21/3
15, 7/3
5, 7/5
1, 7/7
1, 1
MMC = 2.2.2.3.3.5.7 = 2520
MMC = 2520
MDC = 3
b)
140, 168, 240/2
70, 84, 120/2
35, 42, 60/2
35, 21, 30/2
35, 21, 15/3
35, 7, 5/5
7, 7, 1 /7
1, 1, 1
MMC = 2.2.2.2.3.5.7 = 1680
MMC = 1680
MDC = 2.2 = 4
MDC = 4
c)
30, 175, 980/2
15, 175, 490/2
15, 175, 245/3
5, 175, 245/5
1, 35, 49/5
1, 7, 49/7
1, 1, 7/7
1, 1, 1
MMC = 2.2.3.5.5.7.7 = 14700
MMC = 14700
MDC = 5
Espero ter ajudado.
