Answer 1

1. a) D12= {1, 2, 3, 4, 6, 12}; D8= {1, 2, 4, 8}

cmmdc (12, 8)= 4

b) D10= {1, 2, 5, 10}; D25= {1, 5, 25}

cmmd(10, 25)= 5

c) D18= {1, 2, 3, 6, 9, 18}; D24= {1, 2, 3, 4, 6, 8, 12, 24}

cmmdc(18, 24) = 6

d) D15= {1, 3, 5, 15}; D25={1, 5, 25}

cmmdc(15, 25)= 5

e) D20= {1, 2, 4, 5, 10, 20}; D28= {1, 2, 4, 7, 14, 28}

cmmdc(20, 28)= 2

f) D8= {1, 2, 4, 8}; D26= {1, 2, 13, 26}

cmmdc(8, 26)= 2

g) D24= {1, 2, 3, 4, 6, 8, 12, 24}; D22= {1, 2, 11, 22}

cmmdc (24, 22)= 2

2. a)108= 2²·3³; 45= 3²·5 => cmmdc=9

b) 57=3·19 ; 38=2·19 => cmmdc=19

c) 120=2³·3·5 ; 48=2^4·3> cmmdc=24

d) 42=2·3·7 ; 54=2·3³=> cmmdc=6

e) 182=2·7·13 ;42=2·3·7 => cmmdc=14

f) 24=23·3 ; 36=22·32 => cmmdc=12

3. a) cmmdc (36, 16, 48)= 4

b) cmmdc (8, 24, 36)= 4

c) cmmdc (15, 36, 12)= 3

d) cmmdc (20, 30, 40)= 10

e) cmmdc (126, 162, 270)= 18

f) cmmdc (360, 2700, 630)= 30

Sper ca te-am ajutat si nu am gresit pe undeva din neatentie!
