Answer 1

Resposta:

A) 24

B) 72

C) 336

D) 720

Explicação passo-a-passo:

a) 8,12

$8,12|2 \\ 4,6|2 \\ 2,3|2 \\ 1,3|3 \\ 1,1 -$

2x2x2x3= 24

b) 18,24

$18,24|2 \\ 9,12|2 \\ 9,6|2 \\ 9,3|3 \\ 3,1|3 \\ 1,1 -$

2x2x2x3x3= 72

c) 14,16,21

$14,16,21|2 \\ 7,8,21|2 \\ 7,4,21|2 \\ 7,2,21|2 \\ 7,1,21|3 \\ 7,1,7|7 \\ 1,1,1 -$

2x2x2x2x3x7= 336

d)6,9,15,16

$6,9,15,16|2 \\ 3,9,15,8|2 \\ 3,9,15,4|2 \\ 3,9,15,2|2 \\ 3,9,15,1|3 \\ 1,3,5,1|3 \\ 1,1,5,1|5 \\ 1,1,1,1 -$

2x2x2x2x3x3x5= 720
