Therefore, GCD of numbers 639, 710, 144, 357 is 1

Given Input Data is 639, 710, 144, 357

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

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 710 is 2 x 5 x 71

Prime Factorization of 144 is 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 357 is 3 x 7 x 17

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(639, 710) = 6390

GCD(639, 710) = ( 639 x 710 ) / 6390

GCD(639, 710) = 453690 / 6390

GCD(639, 710) = 71

Step2:

Here we consider the GCD from the above i.e. 71 as first number and the next as 144

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

LCM(71, 144) = 10224

GCD(71, 144) = ( 71 x 144 ) / 10224

GCD(71, 144) = 10224 / 10224

GCD(71, 144) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 357

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

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

GCD(1, 357) = 357 / 357

GCD(1, 357) = 1

GCD of 639, 710, 144, 357 is 1
