Given numbers are 126, 416, 420, 591

The list of prime factors of all numbers are

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

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 591 are 3 x 197

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

Given numbers are 126, 416, 420, 591

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

Apply this formula for all numbers.

Step1:

LCM(126, 416) = 26208

GCD(126, 416) = ( 126 x 416 ) / 26208

= 126 / 416

= 126

Step2:

LCM(2, 420) = 420

GCD(2, 420) = ( 2 x 420 ) / 420

= 2 / 420

= 2

Step3:

LCM(2, 591) = 1182

GCD(2, 591) = ( 2 x 591 ) / 1182

= 2 / 591

= 2

So, Greatest Common Divisor of 126, 416, 420, 591 is 1
