Question 17

Common factor between $17abc,34a{b}^2,51a^{2}b$ is
a) $17abc$
b) $17ab$
c) $17ac$
d) $17a^2{b}^{2}c$

Answer 1

b) $17ab$

$17abc=17\times a\times b\times c34a{b}^2=2\times 17\times a\times b\times b51a^{2}b=3\times 17\times a\times a\times b$

Now, collecting the common factors, we get $17\times a\times b=17ab$
