a)184 ;144 ;84
b)28 ;21
c)77;121
d)150;120

Answer 1

a)184 ;144 ;84
184=2³x23
144=2^4x3²
84=2²x3x7
cmmdc(184,144,84)=2²
cmmmc(184,144,84)=2^4x3²x7x23=20445

b)28 ;21
28=2²x7
21=3x7
cmmdc(28,21)=7
cmmmc(28,21)=2²x3x7=84

c)77;121
77=7x11
121=11²
cmmdc(77,121)=11
cmmmc (77, 121)=7x11²=847

d)150;120
150=2x3x5²
120=2³x3x5
cmmdc(150,120)=2x3x5=30
cmmmc(120,150)=2³x3x5²=600
