GCF of 6 and 8
GCF of 6 and 8
The greatest common factor (GCF) of 6 and 8 is 2. This simplest way to determine the GCF is through listing the factors of each number and identifying the largest number common to both lists. The factors of 6 are 1, 2, 3, and 6, while the factors of 8 are 1, 2, 4, and 8. The common factors are 1 and 2, with 2 being the highest, making it the GCF of 6 and 8. This method is straightforward and effective, especially for smaller numbers, providing a clear path to identifying the greatest common factor without the need for complex calculations or algorithms.
GCF of 6 and 8
GCF of 6 and 8 is 2.
GCF of 6 and 8 by Prime Factorization Method.
To find the greatest common factor (GCF) of 6 and 8 using the prime factorization method:
Step 1: Prime factorize both numbers:
For 6: 6 = 2 × 3
For 8: 8 = 2³
Step 2: Identify the common prime factors and their lowest powers:
The common prime factor between 6 and 8 is 2. The lowest power of 2 in the factorizations is 2¹.
Step 3: Multiply the common prime factors with their lowest powers to determine the GCF:
GCF = 2¹ = 2
Therefore, the greatest common factor (GCF) of 6 and 8 by the prime factorization method is 2.
GCF of 6 and 8 by Long Division Method.
To find the greatest common factor (GCF) of 6 and 8 using the long division method:
Step 1: Start by dividing the larger number (8) by the smaller number (6).
8 ÷ 6 =1 with a remainder of 2.
Step 2: Then, take the divisor (6) and divide it by the remainder (2).
6 ÷ 2 = 3 with a remainder of 0.
Since the remainder is now 0, the division process stops here.
Step 3: The divisors at this step, where the remainder becomes zero, is the greatest common factor (GCF).
GCF = 2.
Therefore, the greatest common factor (GCF) of 6 and 8 by the long division method is 2.
GCF of 6 and 8 by Listing Common Factors.
To find the greatest common factor (GCF) of 6 and 8 by listing common factors:
Step 1: List the factors of each number.
Factors of 6: 1, 2, 3, 6
Factors of 8: 1, 2, 4, 8
Step 2: Identify the common factors.
Common factors: 1, 2
Step 3: Determine the greatest common factor.
The highest number in the list of common factors is 2.
