## 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**.
