Created by: Team Maths - Examples.com, Last Updated: May 29, 2024

## GCF of 6 and 10

To find the GCF of 6 and 10, you can use several methods. One way is by listing the factors: the factors of 6 are 1, 2, 3, and 6, while the factors of 10 are 1, 2, 5, and 10. The common factors are 1 and 2, so the GCF is 2. Another method is the Euclidean algorithm, where you repeatedly divide and take remainders: 10 ÷ 6 is 1 with a remainder of 4, then 6 ÷ 4 is 1 with a remainder of 2, and finally 4 ÷ 2 is 2 with a remainder of 0, confirming the GCF is 2. Prime factorization also works: 6 is 2 × 3, and 10 is 2 × 5; the only common prime factor is 2, so the GCF is 2.

## Methods to Find GCF of 6 and 10

1. Prime Factorization Method
2. Long Division Method
3. Listing Common Factors

## GCF of 6 and 10 by Prime Factorization Method.

To find the Greatest Common Factor (GCF) of 6 and 10 using the prime factorization method, follow these steps:

### Step 1: Find the prime factorization of each number

Prime factorization of 6:

6 = 2 × 3

Prime factorization of 10:

10 = 2 × 5

### Step 2: Identify the common prime factors

• The common prime factor of 6 and 10 is 2.

### Step 3: Multiply the common prime factors

Since the only common prime factor is 2, the GCF is 2.

## GCF of 6 and 10 by Long Division Method.

To find the Greatest Common Factor (GCF) of 6 and 10 using the long division method, follow these steps:

### Step 1: Divide the larger number by the smaller number

10 ÷ 6 = 1 with a remainder of 4.

### Step 2: Replace the larger number with the smaller number, and the smaller number with the remainder

Now, we have 6 and 4.

### Step 3: Repeat the division

6 ÷ 4 = 1 with a remainder of 2.

### Step 4: Continue the process

4 ÷ 2 = 2 with a remainder of 0.

### Step 5: When the remainder is 0, the divisor is the GCF

The last non-zero remainder is 2. So, the GCF of 6 and 10 is 2.

## GCF of 6 and 10 by Listing Common Factors.

To find the Greatest Common Factor (GCF) of 6 and 10 by listing common factors, follow these steps:

Factors of 6:

• 1, 2, 3, 6

Factors of 10:

• 1, 2, 5, 10

### Step 2: Identify the common factors

Common factors of 6 and 10:

• 1, 2

### Step 3: Determine the greatest common factor

The largest common factor is 2. Therefore, the GCF of 6 and 10 is 2.
