We found the divisors of 53, 711, 206, 620 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 53, 711, 206, 620 is 1.

Therefore, GCD of numbers 53, 711, 206, 620 is 1

Given Input Data is 53, 711, 206, 620

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

Prime Factorization of 53 is 53

Prime Factorization of 711 is 3 x 3 x 79

Prime Factorization of 206 is 2 x 103

Prime Factorization of 620 is 2 x 2 x 5 x 31

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(53, 711) = 37683

GCD(53, 711) = ( 53 x 711 ) / 37683

GCD(53, 711) = 37683 / 37683

GCD(53, 711) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 206

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

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

GCD(1, 206) = 206 / 206

GCD(1, 206) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 620

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

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

GCD(1, 620) = 620 / 620

GCD(1, 620) = 1

GCD of 53, 711, 206, 620 is 1
