Given Input Data is 220, 544, 957, 543

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

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 544 is 2 x 2 x 2 x 2 x 2 x 17

Prime Factorization of 957 is 3 x 11 x 29

Prime Factorization of 543 is 3 x 181

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(220, 544) = 29920

GCD(220, 544) = ( 220 x 544 ) / 29920

GCD(220, 544) = 119680 / 29920

GCD(220, 544) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 957

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

LCM(4, 957) = 3828

GCD(4, 957) = ( 4 x 957 ) / 3828

GCD(4, 957) = 3828 / 3828

GCD(4, 957) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 543

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

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

GCD(1, 543) = 543 / 543

GCD(1, 543) = 1

GCD of 220, 544, 957, 543 is 1
