Therefore, GCD of numbers 202, 689, 511 is 1

Given Input Data is 202, 689, 511

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

Prime Factorization of 202 is 2 x 101

Prime Factorization of 689 is 13 x 53

Prime Factorization of 511 is 7 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(202, 689) = 139178

GCD(202, 689) = ( 202 x 689 ) / 139178

GCD(202, 689) = 139178 / 139178

GCD(202, 689) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 511

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

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

GCD(1, 511) = 511 / 511

GCD(1, 511) = 1

GCD of 202, 689, 511 is 1
