What is the greatest common factor of 45x^3, 24x^2, and 16x?

Phoenix [80]

Answer:

$\huge\boxed{\sf GCF = x}$

Step-by-step explanation:

<u>Firstly we'll factorize the terms:</u>

45x³ = 3 * 3 * 5 * x * x * x

24x² = 2 * 2 * 2 * 3 * x * x

16x = 2 * 2 * 2 * 2 * x

<u>The factor which is common in all three terms is:</u>

= x

Hence GCF = x

$\rule[225]{225}{2}$

Hope this helped!
