D)120
E)36​

Answer 1

1- calcule a soma e total de divisores dos número abaixo:
A)40
D(40)= (1,2,4,5,8,10,20,40)
S = 3+9+18+60
S = 12+78
S = 90
___________

B)300
D (300)= (1,2,3,4,5,6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300)
S = 10+21+27+125+135+250+300
S = 58 + 260 + 550
S = 318 + 550
S = 868
____________

C)80
D(80)= (1,2,4,5,8, 10, 16, 20, 40, 80)
S = 20 + 46+ 120
S = 140 + 46
S = 186
__________

D)120
D(120)= (1,2,3,4,5,6,8,10,12,15,20, 24, 30, 40, 60,120)
S = 10+29+47+94+180
S = 39+141+180
S = 180+180
S = 360
_____________

E)36​
D(36)= (1,2,3,4,6,9,12,18,36)
S = (3+7+15+30+36)
S = 10+45+36
S = 55+36
S = 91
