Answer 1

Resposta:

a) $6, 8, 12 | 2\\3, 4, 6 |2\\3, 2, 3| 2\\3, 1, 3|3\\1, 1, 1| 2^{3} .3= 24$

g)$28, 48| 2\\14, 24| 2\\7, 12| 2\\7, 6 | 2\\ 7, 3|3\\ 7, 1|7\\ 1, 1| 2^{4}.3.7=336$

b)$2, 14, 21|2\\1, 7, 21| 7\\1, 1, 3| 3\\1, 1, 1| 2.7.3=42$

h)$3, 12, 18|2\\3, 6, 9|3\\1, 2, 3|3\\1, 2, 1| 2\\1, 1, 1| 2.2.3.3=36$

c)$4, 6, 12|2\\2, 3, 6|2\\1, 3, 3|3\\1, 1, 1|2.2.3=12$

i)$5, 15, 25| 5\\1, 3, 5|5\\1, 3, 1|3\\1, 1, 1|5.5.3=75$

d)$36, 48|2\\18, 24|2\\9, 12| 2\\9, 6| 2\\9, 3| 3\\3, 1| 3\\1, 1|2^{4} .3^{2}=144$

j) $8, 16, 32|2\\4, 8, 16|2\\2, 4, 8|2\\1, 2, 4|2\\1, 1, 2|2\\1, 1, 1|2^{5} =32$

e)$50, 75|5\\10, 15|5\\2, 3|2\\1, 3| 3\\1, 1| 5.5.2.3=150$

$8, 9, 15|2\\4, 9, 15|2\\2, 9, 15|2\\1, 9, 15|3\\1, 3, 5|3\\1, 1, 5| 5\\1,1,1|2^{3} .3^{2} .5=360$

f)$3, 12, 15|3\\1, 4, 5|2\\1, 2, 5|2\\1, 1, 5|5\\1, 1, 1| 3.2.2.5=60$

O número após o traço está dividindo os anteriores e quando resta somente 1, 1, 1, multiplica-se os divisores.

Espero ter ajudado ^-^
