Given numbers are 109, 638, 580, 476

The list of prime factors of all numbers are

Prime factors of 109 are 109

Prime factors of 638 are 2 x 11 x 29

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 476 are 2 x 2 x 7 x 17

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

Given numbers are 109, 638, 580, 476

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

Apply this formula for all numbers.

Step1:

LCM(109, 638) = 69542

GCD(109, 638) = ( 109 x 638 ) / 69542

= 109 / 638

= 109

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 476) = 476

GCD(1, 476) = ( 1 x 476 ) / 476

= 1 / 476

= 1

So, Greatest Common Divisor of 109, 638, 580, 476 is 1
