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

Answer:Since 60x4y7,45x5y5,75x3y 60 x 4 y 7, 45 x 5 y 5, 75 x 3 y contain both numbers and variables, there are two steps to find the GCF (HCF)

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

Answer: 15x^3
