Find the greatest common factor for the group of terms. -66a^2, 11a^5
11a^5
-66a^2 = -1 * 11 * 2 * 3 * a^2
11 a^5 = 11 * a^2 * a^3
common are a^2 and 11
so I think
11 a^2
To find the greatest common factor (GCF) for the group of terms -66a^2 and 11a^5, we need to determine the largest factor that both terms have in common. Here are the steps to find the GCF:
Step 1: Identify the factors of each term:
- For -66a^2, the factors are: -1, -2, -3, -6, -11, -22, -33, -66, a, a^2.
- For 11a^5, the factors are: 1, 11, a, a^2, a^3, a^4, a^5.
Step 2: Determine the common factors:
- The common factors for both terms are: 1, a.
Step 3: Find the largest common factor:
- The largest common factor is a.
Therefore, the greatest common factor for the group of terms -66a^2 and 11a^5 is a.
