Question

НОК(8,16и20) с ришением!)

 

Answer 1

К (8) = {8,16,32,40,48,56,64,72,80}
К (16) = {16,32,48,64,80}
К (20) = {20,40,60,80}

НОК(8,16,20) = 80 

Еще вариант:
8=2*2*2
16=2*2*2*2
20=2*2*5

НОК(8,16,20) = 2*2*2*2*5=80

Answer 2

НОК(8,16И20)=20*5=100

8/2=4/2=2/2=1; 16/2=8/2=4/2=2/2=1; 20/2=10/2=5/5=1
