Question

Choose a common factor of $17abc,34a{b}^2,$ and $51a^{2}b$ from the given options.

• A. $17ab$
• B. $17a^2{b}^{2}c$
• C. $17bc$
• D. $17ac$

Answer 1

The correct option is A $17ab$

$17abc=17\times a\times b\times c$
$34a{b}^2=2\times 17\times a\times b\times b$
$51a^{2}b=3\times 17\times a\times a\times b$

A common factor of $17abc,34a{b}^2,$ and $51a^{2}b$ is $17ab$.
