Question

Se dau Nr 1404 si 972
a) calculați c.m.m.d.c al numerelor date
b) calculați c.m.m.m.c al numerelor date
Va rog dau coroană

Answer 1

1404=2²×3³×13

972=2²×3⁵

a) (1404,972)=2²×3³=108

b) [1404,972]=2²×3⁵×13=12636

Answer 2

a)
$1404 = {2}^{2} \times {3}^{3} \times 13$
$972 = {2}^{2} \times {3}^{5}$
$cmmdc(1404 \: si \: 972) = {2}^{2} \times {3}^{3} = 4 \times 27 = 108$
b)
$cmmmc(1404 \: si \: 972) = {2}^{2} \times {3}^{5} \times 13 = 972 \times 13 = 12636$
Succes in continuare:))
