Buna!
[tex]\large\bf a)~~\dfrac{7}{2} ~~si ~~\dfrac{5}{4}\longrightarrow \boxed{\bf 4~numitor~ comun}[/tex]
2 = 2¹
4 = 2²
cmmmc [2, 4] = 2² = 4
=======================
[tex]\large\bf b)~~\dfrac{5}{8} ~~si ~~\dfrac{3}{4}\longrightarrow \boxed{\bf 8~numitor~ comun}[/tex]
8 = 2³
4 = 2²
cmmmc [8, 4] = 2³ = 8
=======================
[tex]\large\bf c)~~\dfrac{8}{3} ~~si ~~\dfrac{7}{6}\longrightarrow \boxed{\bf 6~numitor~ comun}[/tex]
3 = 3¹
6 = 2 × 3
cmmmc [3, 6] = 2 × 3 = 6
=======================
[tex]\large\bf d)~~\dfrac{8}{9} ~~si ~~\dfrac{4}{3}\longrightarrow \boxed{\bf 9~numitor~ comun}[/tex]
3 = 3¹
9 = 3²
cmmmc [3, 9] = 3² = 9
