Answer: GCF the 10, 30 and 45 is 5. Explanation:

The GCF of 3 non-zero integers, x(10), y(30) and also 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 various methods for finding the GCF of 10, 30 and also 45.

Long division MethodUsing Euclid's AlgorithmListing typical Factors

### GCF the 10, 30 and also 45 by long Division GCF of 10, 30 and 45 can be represented as GCF the (GCF of 10, 30) and also 45. GCF(10, 30, 45) deserve to be thus calculated by an initial finding GCF(10, 30) using long division and thereafter using this an outcome with 45 to perform long division again.

Step 2: since the remainder = 0, the divisor (10) is the GCF(10, 30) = 10.Step 3: now to find the GCF that 10 and also 45, us will do a long department on 45 and 10.Step 4: for remainder = 0, divisor = 5 ⇒ GCF(10, 45) = 5

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

### GCF of 10, 30 and also 45 by Euclidean Algorithm

As per the Euclidean Algorithm, GCF(X, Y) = GCF(Y, X mod 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 mode 10) = GCF(10, 0)GCF(10, 0) = 10 (∵ GCF(X, 0) = |X|, whereby X ≠ 0)

Steps for 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|, where X ≠ 0)

Therefore, the value of GCF that 10, 30 and also 45 is 5.

### GCF of 10, 30 and 45 through Listing typical Factors

Factors that 10: 1, 2, 5, 10Factors that 30: 1, 2, 3, 5, 6, 10, 15, 30Factors that 45: 1, 3, 5, 9, 15, 45

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

Example 2: calculate the GCF the 10, 30, and 45 utilizing LCM the the offered numbers.

Solution:

Prime administrate of 10, 30 and also 45 is provided as,

10 = 2 × 530 = 2 × 3 × 545 = 3 × 3 × 5

LCM(10, 30) = 30, LCM(30, 45) = 90, LCM(45, 10) = 90, LCM(10, 30, 45) = 90⇒ GCF(10, 30, 45) = <(10 × 30 × 45) × LCM(10, 30, 45)>/⇒ GCF(10, 30, 45) = (13500 × 90)/(30 × 90 × 90)⇒ GCF(10, 30, 45) = 5.Therefore, the GCF that 10, 30 and also 45 is 5.

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

Solution:

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

10 = 2 × 530 = 2 × 3 × 545 = 3 × 3 × 5

∴ LCM of (10, 30), (30, 45), (10, 45), and (10, 30, 45) is 30, 90, 90, and also 90 respectively.Now, LHS = GCF(10, 30, 45) = 5.And, RHS = <(10 × 30 × 45) × LCM(10, 30, 45)>/ = <(13500) × 90>/<30 × 90 × 90>LHS = RHS = 5.Hence verified.
