Given Input Data is 276, 861, 30, 578

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 861 is 3 x 7 x 41

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 578 is 2 x 17 x 17

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, 861) = 79212

GCD(276, 861) = ( 276 x 861 ) / 79212

GCD(276, 861) = 237636 / 79212

GCD(276, 861) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 30

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

LCM(3, 30) = 30

GCD(3, 30) = ( 3 x 30 ) / 30

GCD(3, 30) = 90 / 30

GCD(3, 30) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 578

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

LCM(3, 578) = 1734

GCD(3, 578) = ( 3 x 578 ) / 1734

GCD(3, 578) = 1734 / 1734

GCD(3, 578) = 1

GCD of 276, 861, 30, 578 is 1
