Therefore, GCD of numbers 603, 555, 281, 857 is 1

Given Input Data is 603, 555, 281, 857

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

Prime Factorization of 603 is 3 x 3 x 67

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 281 is 281

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(603, 555) = 111555

GCD(603, 555) = ( 603 x 555 ) / 111555

GCD(603, 555) = 334665 / 111555

GCD(603, 555) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 281

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

LCM(3, 281) = 843

GCD(3, 281) = ( 3 x 281 ) / 843

GCD(3, 281) = 843 / 843

GCD(3, 281) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 857

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

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

GCD(1, 857) = 857 / 857

GCD(1, 857) = 1

GCD of 603, 555, 281, 857 is 1
