Questions: Find the greatest common factor of 25x^4 and 20a^2.

Transcript text: Find the greatest common factor of $25 x^{4}$ and $20 a^{2}$.

Solution

Step 1: Factorize the coefficients

Step 2: Identify the common factors of the coefficients

Step 3: Identify the common variable factors

The variable factors are $ x^4 $ and $ a^2 $.
Since there are no common variables between $ x^4 $ and $ a^2 $, the common variable factor is 1.

The greatest common factor (GCF) of $ 25x^4 $ and $ 20a^2 $ is $ 5 $.
