Therefore, GCD of numbers 325, 520, 621, 734 is 1

Given Input Data is 325, 520, 621, 734

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

Prime Factorization of 325 is 5 x 5 x 13

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 734 is 2 x 367

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(325, 520) = 2600

GCD(325, 520) = ( 325 x 520 ) / 2600

GCD(325, 520) = 169000 / 2600

GCD(325, 520) = 65

Step2:

Here we consider the GCD from the above i.e. 65 as first number and the next as 621

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

LCM(65, 621) = 40365

GCD(65, 621) = ( 65 x 621 ) / 40365

GCD(65, 621) = 40365 / 40365

GCD(65, 621) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 734

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

LCM(1, 734) = 734

GCD(1, 734) = ( 1 x 734 ) / 734

GCD(1, 734) = 734 / 734

GCD(1, 734) = 1

GCD of 325, 520, 621, 734 is 1
