Given Input Data is 525, 155, 738, 243

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

Prime Factorization of 525 is 3 x 5 x 5 x 7

Prime Factorization of 155 is 5 x 31

Prime Factorization of 738 is 2 x 3 x 3 x 41

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

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(525, 155) = 16275

GCD(525, 155) = ( 525 x 155 ) / 16275

GCD(525, 155) = 81375 / 16275

GCD(525, 155) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 738

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

LCM(5, 738) = 3690

GCD(5, 738) = ( 5 x 738 ) / 3690

GCD(5, 738) = 3690 / 3690

GCD(5, 738) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 243

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

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

GCD(1, 243) = 243 / 243

GCD(1, 243) = 1

GCD of 525, 155, 738, 243 is 1
