150
b) 35 =
63
c) 26 =

Answer 1

mdc (48,50)
D(48)= { 1,2,3,4,6,8,12,16,24,48}
D(50)= {1,2,5,10,25,50}
D(84) D(50)= {1,2}
M.D.C(48,50)= 2

mdc(50,60)
D(50)= {1,2,5,10,25,50}
D(60)= {1,2,3,4,5,6,10,12,15,20,30,60}
D(50) D(60)= {1,2,5,10}
M.D.C(50,60)= 10

mdc(48,60)
D(48)= {1,2,3,4,6,8,12,16,24,48}
D(60)= {1,2,3,4,5,6,10,12,15,20,30,60}
D(48)  D(60)= {1,2,3,4,6,12}
M.D.C(48,60)= 12

mdc(48,50,60)
D(48)= {1,2,3,4,6,8,12,16,24,48}
D(50)= {1,2,5,10,25,50}
D(60)= {1,2,3,4,5,6,10,12,15,20,30,60}
D(48)  D(50)  D(60)= {1,2}
M.D.C(48,50,60)= 2
