Menor multiplo comum de
16,20,40,55
E as contas

Answer 1

20, 22, 25|2
10, 11, 25|2
05, 11, 25|5
01, 11, 05|5
01, 11, 01|11
01, 01, 01 --> mmc (20, 22, 25) = 2² x 5² x 11 = 4 x 25 x 11 = 1100

16, 20, 44, 55|2
08, 10, 22, 55|2
04, 05, 11, 55|2
02, 05, 11, 55|2
01, 05, 11, 55|5
01, 01, 11, 11|11
01, 01, 01, 01 --> mmc (16, 25, 44, 55) = 2^4 x 5 x 11 = 16 x 5 x 11 = 80 x 11 = 880

Answer 2

m.m.c(,20,22,55) =2² .5.11=220    m.m.c(16,20,40,55)=2.2.2.2.5.11.= 16.5.11=80.11=880
