What's the greatest common factor of 45x^5 and 60x^3

15x^3

Step-by-step explanation:

45x^5 = 3 * 3 * 5 * x * x * x * x * x

60x^3 = 2 * 2 * 3 * 5 * x * x * x

Now we see which factors are in common (shown in bold face).

45x^5 = 3 * 3 * 5 * x * x * x * x * x

60x^3 = 2 * 2 * 3 * 5 * x * x * x

GCF = 3 * 5 * x * x * x

GCF = 15x^3

15x^3

the value of x is 28.2
