Therefore, GCD of numbers 865, 605, 899, 545 is 1

Given Input Data is 865, 605, 899, 545

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

Prime Factorization of 865 is 5 x 173

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 899 is 29 x 31

Prime Factorization of 545 is 5 x 109

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(865, 605) = 104665

GCD(865, 605) = ( 865 x 605 ) / 104665

GCD(865, 605) = 523325 / 104665

GCD(865, 605) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 899

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

LCM(5, 899) = 4495

GCD(5, 899) = ( 5 x 899 ) / 4495

GCD(5, 899) = 4495 / 4495

GCD(5, 899) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 545

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

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

GCD(1, 545) = 545 / 545

GCD(1, 545) = 1

GCD of 865, 605, 899, 545 is 1
