Therefore, GCD of numbers 620, 965, 357, 461 is 1

Given Input Data is 620, 965, 357, 461

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

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

Prime Factorization of 965 is 5 x 193

Prime Factorization of 357 is 3 x 7 x 17

Prime Factorization of 461 is 461

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(620, 965) = 119660

GCD(620, 965) = ( 620 x 965 ) / 119660

GCD(620, 965) = 598300 / 119660

GCD(620, 965) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 357

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

LCM(5, 357) = 1785

GCD(5, 357) = ( 5 x 357 ) / 1785

GCD(5, 357) = 1785 / 1785

GCD(5, 357) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 461

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

LCM(1, 461) = 461

GCD(1, 461) = ( 1 x 461 ) / 461

GCD(1, 461) = 461 / 461

GCD(1, 461) = 1

GCD of 620, 965, 357, 461 is 1
