Question

va rooooog dau coroana orice​

Answer 1

a) 12 = 2^2×3

28 =2^2×7

cmmmc = [12,28] = 2^2×3×7=84

............................................................

12=2^2×3

28=2^2×7

cmmdc= [12,28] =2^2=4

.............................................................................

b) 128 = 2^7

243 = 11×13

cmmmc = [128,243] = 2^7×11×13=18,304

............................................................................

128 = 2^7

243=11×13

cmmdc = [128,143] =1
