Therefore, GCD of numbers 154, 198, 29, 840 is 1

Given Input Data is 154, 198, 29, 840

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

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 198 is 2 x 3 x 3 x 11

Prime Factorization of 29 is 29

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

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(154, 198) = 1386

GCD(154, 198) = ( 154 x 198 ) / 1386

GCD(154, 198) = 30492 / 1386

GCD(154, 198) = 22

Step2:

Here we consider the GCD from the above i.e. 22 as first number and the next as 29

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

LCM(22, 29) = 638

GCD(22, 29) = ( 22 x 29 ) / 638

GCD(22, 29) = 638 / 638

GCD(22, 29) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 840

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

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

GCD(1, 840) = 840 / 840

GCD(1, 840) = 1

GCD of 154, 198, 29, 840 is 1
