aflati cmmdc si cmmmc al numerelor 140 si 490

Răspuns :

490 = 2 × 5 × 7^2
140 = 2^2 × 5 × 7
cmmmc (490; 140) = 2^2 × 5 × 72 = 980




140 = 2^2 × 5 × 7;
490 = 2 × 5 × 7^2
cmmdc (140; 490) = 2 × 5 × 7 = 70;



cmmmc [140,490]
140=2^2*5*7
490=2*5*7^2
=>[140,490]=7^2*5*2^2=980

cmmdc (140 , 490)
140=2^2*5*7
490=2^2*5*7^2
(140,490)=7*2*5=70
