Given Input Data is 276, 640, 673, 458

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

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

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 673 is 673

Prime Factorization of 458 is 2 x 229

The above numbers do not have any common prime factor. So GCD is 1

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(276, 640) = 44160

GCD(276, 640) = ( 276 x 640 ) / 44160

GCD(276, 640) = 176640 / 44160

GCD(276, 640) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 673

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

LCM(4, 673) = 2692

GCD(4, 673) = ( 4 x 673 ) / 2692

GCD(4, 673) = 2692 / 2692

GCD(4, 673) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 458

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

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

GCD(1, 458) = 458 / 458

GCD(1, 458) = 1

GCD of 276, 640, 673, 458 is 1
