Question

cum pot calcula ex: (115,46)  (30,48) (50,63) (120,300) (240,400)
                               [115,46] [30,48] [50,63] [2400,400]
                              [240,400)

Answer 1

(115,46)=1115=3·5·7
46=2·23 (30,48)=3·2^4=3·2=630=2·3·5
48=3·2^4             ^-putere
(50,63)=150=2·5²
63=3²·7 (120,300) =2²·3·5=60120=2³·3·5
300=3·2²·5²(240,400)=5·2^4=90240=3·5·2^4
400=5²·2^4[115,46]=3·5·7·2·23=4830
 [30,48]=3·2^4·5=240
 [50,63]=2·3²·5²·7=3150
 [2400,400]=2^5·3·5²=2400
2400=2^5·3·5²
400=5²·2^4
[240,400]=2^4·3·5²=1200
