Given numbers are 558, 428, 649, 631

The list of prime factors of all numbers are

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 428 are 2 x 2 x 107

Prime factors of 649 are 11 x 59

Prime factors of 631 are 631

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

Given numbers are 558, 428, 649, 631

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

Apply this formula for all numbers.

Step1:

LCM(558, 428) = 119412

GCD(558, 428) = ( 558 x 428 ) / 119412

= 558 / 428

= 558

Step2:

LCM(2, 649) = 1298

GCD(2, 649) = ( 2 x 649 ) / 1298

= 2 / 649

= 2

Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 558, 428, 649, 631 is 1
