Given Input Data is 430, 540, 70, 276

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

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 540 is 2 x 2 x 3 x 3 x 3 x 5

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 276 is 2 x 2 x 3 x 23

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(430, 540) = 23220

GCD(430, 540) = ( 430 x 540 ) / 23220

GCD(430, 540) = 232200 / 23220

GCD(430, 540) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 70

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

LCM(10, 70) = 70

GCD(10, 70) = ( 10 x 70 ) / 70

GCD(10, 70) = 700 / 70

GCD(10, 70) = 10

Step3:

Here we consider the GCD from the above i.e. 10 as first number and the next as 276

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

LCM(10, 276) = 1380

GCD(10, 276) = ( 10 x 276 ) / 1380

GCD(10, 276) = 2760 / 1380

GCD(10, 276) = 2

GCD of 430, 540, 70, 276 is 2
