Therefore, GCD of numbers 543, 801, 892, 657 is 1

Given Input Data is 543, 801, 892, 657

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

Prime Factorization of 543 is 3 x 181

Prime Factorization of 801 is 3 x 3 x 89

Prime Factorization of 892 is 2 x 2 x 223

Prime Factorization of 657 is 3 x 3 x 73

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(543, 801) = 144981

GCD(543, 801) = ( 543 x 801 ) / 144981

GCD(543, 801) = 434943 / 144981

GCD(543, 801) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 892

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

LCM(3, 892) = 2676

GCD(3, 892) = ( 3 x 892 ) / 2676

GCD(3, 892) = 2676 / 2676

GCD(3, 892) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 657

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

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

GCD(1, 657) = 657 / 657

GCD(1, 657) = 1

GCD of 543, 801, 892, 657 is 1
