Therefore, GCD of numbers 245, 427, 53, 915 is 1

Given Input Data is 245, 427, 53, 915

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

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 427 is 7 x 61

Prime Factorization of 53 is 53

Prime Factorization of 915 is 3 x 5 x 61

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(245, 427) = 14945

GCD(245, 427) = ( 245 x 427 ) / 14945

GCD(245, 427) = 104615 / 14945

GCD(245, 427) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 53

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

LCM(7, 53) = 371

GCD(7, 53) = ( 7 x 53 ) / 371

GCD(7, 53) = 371 / 371

GCD(7, 53) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 915

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

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

GCD(1, 915) = 915 / 915

GCD(1, 915) = 1

GCD of 245, 427, 53, 915 is 1
