Bonsoir,
1800/819
=(600×3)/(273×3)
=600/273
=(200×3)/(91×3)
=200/91 qui est irréductible

Bonsoir
♤ On calcul le PGCD (1800;819) on le décomposant en produit de facteur 1er on a donc :
1.800 = 2^3 × 3^2 × 5^2
819 = 3^2 × 7 × 13
● D'où PGCD (1800;819) = 3^2 = 9
♤ Puis enfin : (1800÷9)/(819÷9) = 200/91
Voilà ^^
