Prime Factorization MethodListing Common FactorsLong Division Method

### GCF of 10 and 12 by Prime Factorization

Prime factorization of 10 and 12 is (2 × 5) and (2 × 2 × 3) respectively. As visible, 10 and 12 have only one common prime factor i.e. 2. Hence, the GCF of 10 and 12 is 2.

### GCF of 10 and 12 by Listing Common Factors

**Factors of 10:** 1, 2, 5, 10**Factors of 12:** 1, 2, 3, 4, 6, 12

There are 2 common factors of 10 and 12, that are 1 and 2. Therefore, the greatest common factor of 10 and 12 is 2.

### GCF of 10 and 12 by Long Division

GCF of 10 and 12 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.

**Step 2:** Since the remainder ≠ 0, we will divide the divisor of step 1 (10) by the remainder (2).

## GCF of 10 and 12 Examples

**Example 1: Find the greatest number that divides 10 and 12 exactly. **

**Solution: **

The greatest number that divides 10 and 12 exactly is their greatest common factor, i.e. GCF of 10 and 12.⇒ Factors of 10 and 12:

Factors of 10 = 1, 2, 5, 10Factors of 12 = 1, 2, 3, 4, 6, 12

Therefore, the GCF of 10 and 12 is 2.

**Example 2: For two numbers, GCF = 2 and LCM = 60. If one number is 10, find the other number.**

**Solution:**

Given: GCF (y, 10) = 2 and LCM (y, 10) = 60∵ GCF × LCM = 10 × (y)⇒ y = (GCF × LCM)/10⇒ y = (2 × 60)/10⇒ y = 12Therefore, the other number is 12.

**Example 3: The product of two numbers is 120. If their GCF is 2, what is their LCM? **

**Solution:**

Given: GCF = 2 and product of numbers = 120∵ LCM × GCF = product of numbers⇒ LCM = Product/GCF = 120/2Therefore, the LCM is 60.
