### GCF the 28 and also 84 by Listing common Factors

Factors the 28: 1, 2, 4, 7, 14, 28Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

There room 6 usual factors that 28 and also 84, that are 1, 2, 4, 7, 14, and also 28. Therefore, the greatest typical factor of 28 and also 84 is 28.

### GCF the 28 and also 84 by 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 = 84 and also Y = 28

GCF(84, 28) = GCF(28, 84 mode 28) = GCF(28, 0)GCF(28, 0) = 28 (∵ GCF(X, 0) = |X|, where X ≠ 0)

Therefore, the worth of GCF that 28 and also 84 is 28.

### GCF of 28 and 84 by long Division GCF of 28 and 84 is the divisor the we gain when the remainder becomes 0 ~ doing long division repeatedly.

Step 2: due to the fact that the remainder = 0, the divisor (28) is the GCF the 28 and 84.

The equivalent divisor (28) is the GCF of 28 and 84.
