Given Input Data is 655, 540, 478, 732

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

Prime Factorization of 655 is 5 x 131

Prime Factorization of 540 is 2 x 2 x 3 x 3 x 3 x 5

Prime Factorization of 478 is 2 x 239

Prime Factorization of 732 is 2 x 2 x 3 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(655, 540) = 70740

GCD(655, 540) = ( 655 x 540 ) / 70740

GCD(655, 540) = 353700 / 70740

GCD(655, 540) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 478

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

LCM(5, 478) = 2390

GCD(5, 478) = ( 5 x 478 ) / 2390

GCD(5, 478) = 2390 / 2390

GCD(5, 478) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 732

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

LCM(1, 732) = 732

GCD(1, 732) = ( 1 x 732 ) / 732

GCD(1, 732) = 732 / 732

GCD(1, 732) = 1

GCD of 655, 540, 478, 732 is 1
