Therefore, GCD of numbers 153, 558, 97, 970 is 1

Given Input Data is 153, 558, 97, 970

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

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 97 is 97

Prime Factorization of 970 is 2 x 5 x 97

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(153, 558) = 9486

GCD(153, 558) = ( 153 x 558 ) / 9486

GCD(153, 558) = 85374 / 9486

GCD(153, 558) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 97

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

LCM(9, 97) = 873

GCD(9, 97) = ( 9 x 97 ) / 873

GCD(9, 97) = 873 / 873

GCD(9, 97) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 970

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

LCM(1, 970) = 970

GCD(1, 970) = ( 1 x 970 ) / 970

GCD(1, 970) = 970 / 970

GCD(1, 970) = 1

GCD of 153, 558, 97, 970 is 1
