Therefore, GCD of numbers 619, 169, 74, 427 is 1

Given Input Data is 619, 169, 74, 427

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

Prime Factorization of 619 is 619

Prime Factorization of 169 is 13 x 13

Prime Factorization of 74 is 2 x 37

Prime Factorization of 427 is 7 x 61

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(619, 169) = 104611

GCD(619, 169) = ( 619 x 169 ) / 104611

GCD(619, 169) = 104611 / 104611

GCD(619, 169) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 74

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

LCM(1, 74) = 74

GCD(1, 74) = ( 1 x 74 ) / 74

GCD(1, 74) = 74 / 74

GCD(1, 74) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 427

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

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

GCD(1, 427) = 427 / 427

GCD(1, 427) = 1

GCD of 619, 169, 74, 427 is 1
