**Answer:** GCF of 4 and also 8 is 4.

**Explanation: **

The GCF of 2 non-zero integers, x(4) and also y(8), is the best positive essence m(4) the divides both x(4) and also y(8) without any remainder.

Let's look in ~ the different methods for finding the GCF of 4 and also 8.

Prime administrate MethodUsing Euclid's AlgorithmListing usual Factors### GCF the 4 and also 8 by element Factorization

Prime administer of 4 and also 8 is (2 × 2) and also (2 × 2 × 2) respectively. As visible, 4 and 8 have common prime factors. Hence, the GCF that 4 and also 8 is 2 × 2 = 4.

### GCF the 4 and also 8 through Euclidean Algorithm

As every the Euclidean Algorithm, GCF(X, Y) = GCF(Y, X mod Y)where X > Y and mod is the modulo operator.

Here X = 8 and Y = 4

GCF(8, 4) = GCF(4, 8 mode 4) = GCF(4, 0)GCF(4, 0) = 4 (∵ GCF(X, 0) = |X|, whereby X ≠ 0)Therefore, the value of GCF the 4 and also 8 is 4.

### GCF that 4 and also 8 by Listing typical Factors

**Factors the 4:**1, 2, 4

**Factors that 8:**1, 2, 4, 8

There are 3 usual factors the 4 and also 8, that space 1, 2, and 4. Therefore, the greatest common factor that 4 and also 8 is 4.

## GCF of 4 and 8 Examples

**Example 1: find the GCF of 4 and also 8, if your LCM is 8. **

**Solution: **

∵ LCM × GCF = 4 × 8⇒ GCF(4, 8) = (4 × 8)/8 = 4Therefore, the greatest common factor that 4 and also 8 is 4.

**Example 2: find the greatest number that divides 4 and also 8 exactly. **

**Solution: **

The best number the divides 4 and 8 precisely is your greatest common factor, i.e. GCF of 4 and 8.⇒ components of 4 and also 8:

Factors that 4 = 1, 2, 4Factors that 8 = 1, 2, 4, 8Therefore, the GCF that 4 and 8 is 4.

**Example 3: For 2 numbers, GCF = 4 and LCM = 8. If one number is 4, discover the various other number.**

**Solution:**

Given: GCF (y, 4) = 4 and LCM (y, 4) = 8∵ GCF × LCM = 4 × (y)⇒ y = (GCF × LCM)/4⇒ y = (4 × 8)/4⇒ y = 8Therefore, the various other number is 8.
