On donne: 1ºr cas: a = 180; b=210; c=2x35x5³; d = 25 x 11 x 5³ x 3³ x 7³ 2eme cas: a=3² x 2 x 7³ x 5; b=2²x 3³ x7; c = 2 x 3² x 7³; d = 2 x 5² x 3 3ème cas: a = 104 ; b=240; c = 375; d = 2 x 5² x 3 Dans chacun des cas ci-dessus, calculer : PPCM (a; b); PPCM (c; d); PPCM (a; c); PPCM (d; b) et PGCD (a; b); PGCD (c; d); PGCD (a; c); PGCD (d; b)
