The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 638 are 2 x 11 x 29

Prime factors of 841 are 29 x 29

Prime factors of 278 are 2 x 139

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

Given numbers are 545, 638, 841, 278

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

Apply this formula for all numbers.

Step1:

LCM(545, 638) = 347710

GCD(545, 638) = ( 545 x 638 ) / 347710

= 545 / 638

= 545

Step2:

LCM(1, 841) = 841

GCD(1, 841) = ( 1 x 841 ) / 841

= 1 / 841

= 1

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 545, 638, 841, 278 is 1
