**Answer:** GCF of 10, 30 and 45 is 5.

**Explanation: **

The GCF of three non-zero integers, x(10), y(30) and z(45), is the biggest positive integer m(5) that divides x(10), y(30) and also z(45) without any type of remainder.

Let's look at the different methods for finding the GCF the 10, 30 and 45.

Long department MethodUsing Euclid's AlgorithmListing usual Factors### GCF that 10, 30 and also 45 by long Division

GCF the 10, 30 and also 45 deserve to be stood for as GCF of (GCF the 10, 30) and 45. GCF(10, 30, 45) have the right to be for this reason calculated by very first finding GCF(10, 30) using long division and afterwards using this result with 45 to carry out long department again.

**Step 2:**due to the fact that the remainder = 0, the divisor (10) is the GCF(10, 30) = 10.

**Step 3:**now to discover the GCF that 10 and also 45, us will perform a long division on 45 and 10.

**Step 4:**because that remainder = 0, divisor = 5 ⇒ GCF(10, 45) = 5

Thus, GCF(10, 30, 45) = GCF(GCF(10, 30), 45) = 5.

### GCF that 10, 30 and 45 through Euclidean Algorithm

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

GCF(10, 30, 45) = GCF(GCF(10, 30), 45)

GCF(30, 10) = GCF(10, 30 mod 10) = GCF(10, 0)GCF(10, 0) = 10 (∵ GCF(X, 0) = |X|, where X ≠ 0)Steps because that GCF(10, 45)

GCF(45, 10) = GCF(10, 45 mod 10) = GCF(10, 5)GCF(10, 5) = GCF(5, 10 mode 5) = GCF(5, 0)GCF(5, 0) = 5 (∵ GCF(X, 0) = |X|, wherein X ≠ 0)Therefore, the value of GCF that 10, 30 and also 45 is 5.

### GCF the 10, 30 and 45 by Listing usual Factors

**Factors the 10:**1, 2, 5, 10

**Factors that 30:**1, 2, 3, 5, 6, 10, 15, 30

**Factors that 45:**1, 3, 5, 9, 15, 45

There space 2 common factors of 10, 30 and also 45, that space 1 and 5. Therefore, the greatest typical factor the 10, 30 and also 45 is 5.

**Example 3: Verify the relation in between the LCM and also GCF of 10, 30 and also 45. **

**Solution:**

The relation in between the LCM and GCF that 10, 30 and also 45 is offered as, GCF(10, 30, 45) = <(10 × 30 × 45) × LCM(10, 30, 45)>/

∴ LCM the (10, 30), (30, 45), (10, 45), and also (10, 30, 45) is 30, 90, 90, and 90 respectively.Now, LHS = GCF(10, 30, 45) = 5.And, RHS = <(10 × 30 × 45) × LCM(10, 30, 45)>/
