alguem sabe o M D C de 40,50 e depois 9,12,15 e depois 16,56,80?????
Soluções para a tarefa
a)MDC(40,50) fatorar 40| 2 50|2
20| 2 25|5
10|2 5|5
5|5 1___
1 _____ 2.5²
2³.5
então MDC (40.50)=2.5=10
b) MDC(9,12,15) 9|3 12|2 15|3
3|3 6|2 5|5
1___ 3|3 1___
3² 1___ 3.5
2² .3
MDC(9,12,15)=3
c) MDC(16,56,80) 16|2 56|2 80|2
8|2 28|2 40|2
4|2 14|2 20|2
2|2 7|7 10|2
1____ 1___ 5|5
(2²)² 2³.7 1___
(2²)².5
MDC(16,56,80)=2³=8
40,50: 2
20, 25, 2
10, 25: 2
5, 25: 5
1,5: 5
1,1 = 2.5 = 10
mdc (40,50) = 10
____________________________________
b)
mdc (9,12,15) = 3
9,12,15: 2
9,6,15: 2
9,3, 15: 3
3,1,5: 3
1,1,5: 5
1,1,1
******************************************
c)
16,56,80 : 2
8,28, 40: 2
4,14, 20 : 2
2,7,10: 2
1,7,5: 5
1,7,1: 7
1,1,1 = 2.2.2 = 8
mdc (16,56,80) = 8
