Therefore, GCD of numbers 212, 548, 685, 143 is 1

Given Input Data is 212, 548, 685, 143

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

Prime Factorization of 212 is 2 x 2 x 53

Prime Factorization of 548 is 2 x 2 x 137

Prime Factorization of 685 is 5 x 137

Prime Factorization of 143 is 11 x 13

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(212, 548) = 29044

GCD(212, 548) = ( 212 x 548 ) / 29044

GCD(212, 548) = 116176 / 29044

GCD(212, 548) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 685

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

LCM(4, 685) = 2740

GCD(4, 685) = ( 4 x 685 ) / 2740

GCD(4, 685) = 2740 / 2740

GCD(4, 685) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 143

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

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

GCD(1, 143) = 143 / 143

GCD(1, 143) = 1

GCD of 212, 548, 685, 143 is 1
