Given Input Data is 276, 390, 574, 857

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 390 is 2 x 3 x 5 x 13

Prime Factorization of 574 is 2 x 7 x 41

Prime Factorization of 857 is 857

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, 390) = 17940

GCD(276, 390) = ( 276 x 390 ) / 17940

GCD(276, 390) = 107640 / 17940

GCD(276, 390) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 574

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

LCM(6, 574) = 1722

GCD(6, 574) = ( 6 x 574 ) / 1722

GCD(6, 574) = 3444 / 1722

GCD(6, 574) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 857

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

LCM(2, 857) = 1714

GCD(2, 857) = ( 2 x 857 ) / 1714

GCD(2, 857) = 1714 / 1714

GCD(2, 857) = 1

GCD of 276, 390, 574, 857 is 1
