Question

calculati cmmdc si cmmmc
a) 25,45
b)28,36
c)14,15
d)125,300
e)480,250​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

25 = 5^2

45 = 3^2 * 5

cmmdc = 5

cmmmc = 3^2 * 5^2 = 225

b)

28 = 2^2 * 7

36 = 2^2 * 3^2

cmmdc = 2^2 = 4

cmmmc = 2^2*3^2*7 = 252

c)

14 = 2*7

15 = 3*5

cmmdc = 1

cmmmc = 2*3*5*7 = 210

d)

125 = 5^3

300 = 2^2*3*5^2

cmmdc = 5^2 = 25

cmmmc = 2^2*3*5^3 = 1500

e)

480 = 2^5*3*5

250 = 2*5^3

cmmdc = 2*5 = 10

cmmmc = 2^5*3*5^3 = 12000
