Given numbers are 639, 431, 630, 126

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 431 are 431

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 126 are 2 x 3 x 3 x 7

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

Given numbers are 639, 431, 630, 126

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

Apply this formula for all numbers.

Step1:

LCM(639, 431) = 275409

GCD(639, 431) = ( 639 x 431 ) / 275409

= 639 / 431

= 639

Step2:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 639, 431, 630, 126 is 1
