Given numbers are 695, 420, 608, 254

The list of prime factors of all numbers are

Prime factors of 695 are 5 x 139

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

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

Prime factors of 254 are 2 x 127

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

Given numbers are 695, 420, 608, 254

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

Apply this formula for all numbers.

Step1:

LCM(695, 420) = 58380

GCD(695, 420) = ( 695 x 420 ) / 58380

= 695 / 420

= 695

Step2:

LCM(5, 608) = 3040

GCD(5, 608) = ( 5 x 608 ) / 3040

= 5 / 608

= 5

Step3:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

So, Greatest Common Divisor of 695, 420, 608, 254 is 1
