Answer 1

Break down each expression and then look at the common terms...

$\tt \: 9 = 1×3×3 \\ \sf \: 5 {b}^{3} = 1 \times 5\times b \times b \times b$

• Looking at the common factors

➪ The common factor is 1, Therefore their GCF is 1...

Answer 2

• 9=3×3×3×1
• 5b^3=5×b^3×1

Greatest common factor is 1
