Aflati c.m.m.d.c ale nr 4380 si 6408;b)4422250 SI 72200;C)2488 SI 5340;D)728,2156 SI 2744

Answer 1

a)
omun
cmmdc (4.380; 6.408) = ?
4.380 = 2² * 3 * 5 * 73;
6.408 = 2³ * 3² * 89;
cmmdc (4.380; 6.408) = 2² * 3 = 12
b)

cmmdc (4.422.250; 72.200) = ?
4.422.250 = 2 * 5³ *7² *192;
72.200 = 2² * 5² * 192;

cmmdc (4.422.250; 72.200) = 2 * 5² * 192 = 18.050

c)

cmmdc (2.488; 5.340) = ? :
2.488 = 2² * 311
5.340 = 2² * 3 * 5 * 89
cmmdc (2.488; 5.340) = 2²= 4
d)
728,2156 SI 2744

728 = 2³* 7 * 13
2156 =  2² * 7² * 11
2.744 = 2³ * 7³

cmmdc (728;2156;2744) = 2²*7=28
