question\nidentify the greatest common factor of 18 and 36bc.
Answer
Explanation:
Step1: Prime - factorize 18
$18 = 2\times3^{2}$
Step2: Prime - factorize 36bc
$36bc=2^{2}\times3^{2}\times b\times c$
Step3: Find common factors
The common factors of 18 and 36bc are 2 and $3^{2}$.
Step4: Calculate GCF
The GCF is $2\times3^{2}=18$.
Answer:
18
