So the Greatest Common Divisior 28, 26, 74 is 2.

Therefore, GCD of numbers 28, 26, 74 is 2

Given Input Data is 28, 26, 74

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 26 is 2 x 13

Prime Factorization of 74 is 2 x 37

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(28, 26) = 364

GCD(28, 26) = ( 28 x 26 ) / 364

GCD(28, 26) = 728 / 364

GCD(28, 26) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 74

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(2, 74) = 74

GCD(2, 74) = ( 2 x 74 ) / 74

GCD(2, 74) = 148 / 74

GCD(2, 74) = 2

GCD of 28, 26, 74 is 2
