Question

The common factor of $14a^{2}b$ and $35a^4{b}^2$ is

• A. $a^4{b}^2$
• B. $35a^4{b}^2$
• C. $14a^{2}b$
• D. $7a^{2}b$

Answer 1

Answer: (D)

$14a^{2}b=2\times 7\times a\times a\times b$
$35a^4{b}^2=5\times 7\times a\times a\times a\times a\times b\times b$
$\text{ Common factor }=7a^{2}b$
