Given numbers are 639, 600, 809, 242

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 600 are 2 x 2 x 2 x 3 x 5 x 5

Prime factors of 809 are 809

Prime factors of 242 are 2 x 11 x 11

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 639, 600, 809, 242

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(639, 600) = 127800

GCD(639, 600) = ( 639 x 600 ) / 127800

= 639 / 600

= 639

Step2:

LCM(3, 809) = 2427

GCD(3, 809) = ( 3 x 809 ) / 2427

= 3 / 809

= 3

Step3:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

So, Greatest Common Divisor of 639, 600, 809, 242 is 1
