Explicație pas cu pas:
[tex][9,12] = [ {3}^{2} , {2}^{2} \times 3]= {2}^{2} \times {3}^{2} = 36[/tex]
[tex][24,40] = [{2}^{3} \times 3 , {2}^{3} \times 5] = {2}^{3} \times 3 \times 5 = 120[/tex]
[tex][35,56] =[5 \times 7, {2}^{3} \times 7] = {2}^{3} \times 5 \times 7 = 280[/tex]
[tex][105,25] = [3 \times 5 \times 7, {5}^{2}] =3 \times {5}^{2} \times 7 = 525[/tex]
