### GCF the 18 and also 30 by lengthy Division GCF of 18 and 30 is the divisor that we gain when the remainder becomes 0 after ~ doing long division repeatedly.

Step 2: since the remainder ≠ 0, we will certainly divide the divisor of action 1 (18) through the remainder (12).Step 3: Repeat this process until the remainder = 0.

The equivalent divisor (6) is the GCF the 18 and 30.

### GCF of 18 and also 30 through Listing common Factors Factors that 18: 1, 2, 3, 6, 9, 18Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

There space 4 common factors the 18 and 30, that space 1, 2, 3, and also 6. Therefore, the greatest common factor that 18 and 30 is 6.

### GCF the 18 and 30 by Euclidean Algorithm

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

Here X = 30 and also Y = 18

GCF(30, 18) = GCF(18, 30 mod 18) = GCF(18, 12)GCF(18, 12) = GCF(12, 18 mod 12) = GCF(12, 6)GCF(12, 6) = GCF(6, 12 mod 6) = GCF(6, 0)GCF(6, 0) = 6 (∵ GCF(X, 0) = |X|, whereby X ≠ 0)

Therefore, the worth of GCF that 18 and also 30 is 6.
