Given numbers are 639, 462, 627, 254

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 627 are 3 x 11 x 19

Prime factors of 254 are 2 x 127

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

Given numbers are 639, 462, 627, 254

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

Apply this formula for all numbers.

Step1:

LCM(639, 462) = 98406

GCD(639, 462) = ( 639 x 462 ) / 98406

= 639 / 462

= 639

Step2:

LCM(3, 627) = 627

GCD(3, 627) = ( 3 x 627 ) / 627

= 3 / 627

= 3

Step3:

LCM(3, 254) = 762

GCD(3, 254) = ( 3 x 254 ) / 762

= 3 / 254

= 3

So, Greatest Common Divisor of 639, 462, 627, 254 is 1
