Given numbers are 634, 478, 780, 471

The list of prime factors of all numbers are

Prime factors of 634 are 2 x 317

Prime factors of 478 are 2 x 239

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 471 are 3 x 157

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

Given numbers are 634, 478, 780, 471

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

Apply this formula for all numbers.

Step1:

LCM(634, 478) = 151526

GCD(634, 478) = ( 634 x 478 ) / 151526

= 634 / 478

= 634

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 471) = 942

GCD(2, 471) = ( 2 x 471 ) / 942

= 2 / 471

= 2

So, Greatest Common Divisor of 634, 478, 780, 471 is 1
