Question

por favor preciso de ajuda

mdc(40,16)
mdc (21,28)
mdc (15,20,30)
$por favor$

Answer 1

$40 = 2^{3} . 5$
$16 = 2^{4}$
$MDC(40, 16) = 2^{3} = 8$

$21 = 3 . 7$
$28 = 2^{2} . 7$
$MDC(21, 28) = 7$

$15 = 3 . 5$
$20 = 2 ^{2} . 5$
$30 = 2 . 3 . 5$
$MDC(15, 20, 30) = 5$

Answer 2

Resposta:d(16)=1,2,4,8,,16d ; ;;
D(40)=1,2,4,5,8,10,20,40;
D(21)=1,3,7,21;
D(28)=1,2,4,14,28;
D(15)=1,3,15;
D(20)=1,2,4,5,10,20
D(30)=1,2,3,5,6,10,15,30.
