Prime Factorization Gcf
1. **Problem:** Find the prime factorization of 48 and 60 using exponents, then find the greatest common factor (GCF).
2. Prime factorization of 48:
$$48 = 2 \times 24 = 2 \times 2 \times 12 = 2^3 \times 6 = 2^4 \times 3 = 2^4 \times 3^1$$
3. Prime factorization of 60:
$$60 = 2 \times 30 = 2^2 \times 15 = 2^2 \times 3 \times 5 = 2^2 \times 3^1 \times 5^1$$
4. Find GCF by taking the minimum power of each common prime factor:
$$\text{GCF} = 2^{\min(4,2)} \times 3^{\min(1,1)} = 2^2 \times 3^1 = 4 \times 3 = 12$$
5. **Problem:** Find the prime factorization of 84 and 126 using exponents, then find the GCF.
6. Prime factorization of 84:
$$84 = 2 \times 42 = 2^2 \times 21 = 2^2 \times 3 \times 7 = 2^2 \times 3^1 \times 7^1$$
7. Prime factorization of 126:
$$126 = 2 \times 63 = 2^1 \times 3^2 \times 7^1$$
8. Find GCF by taking the minimum power of each common prime factor:
$$\text{GCF} = 2^{\min(2,1)} \times 3^{\min(1,2)} \times 7^{\min(1,1)} = 2^1 \times 3^1 \times 7^1 = 42$$
9. **Problem:** Find the prime factorization of 150 and 210 using exponents, then find the GCF.
10. Prime factorization of 150:
$$150 = 2 \times 75 = 2^1 \times 3 \times 25 = 2^1 \times 3^1 \times 5^2$$
11. Prime factorization of 210:
$$210 = 2 \times 105 = 2^1 \times 3 \times 35 = 2^1 \times 3^1 \times 5 \times 7 = 2^1 \times 3^1 \times 5^1 \times 7^1$$
12. Find GCF by taking the minimum power of each common prime factor:
$$\text{GCF} = 2^{\min(1,1)} \times 3^{\min(1,1)} \times 5^{\min(2,1)} = 2^1 \times 3^1 \times 5^1 = 30$$
13. **Problem:** Find the prime factorization of 64 and 96 using exponents, then find the GCF.
14. Prime factorization of 64:
$$64 = 2^6$$
15. Prime factorization of 96:
$$96 = 2^5 \times 3^1$$
16. Find GCF by taking the minimum power of each common prime factor:
$$\text{GCF} = 2^{\min(6,5)} = 2^5 = 32$$
**Final answers:**
- For 48 and 60, GCF = 12
- For 84 and 126, GCF = 42
- For 150 and 210, GCF = 30
- For 64 and 96, GCF = 32
