Given numbers are 254, 221, 680, 655

The list of prime factors of all numbers are

Prime factors of 254 are 2 x 127

Prime factors of 221 are 13 x 17

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 655 are 5 x 131

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

Given numbers are 254, 221, 680, 655

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

Apply this formula for all numbers.

Step1:

LCM(254, 221) = 56134

GCD(254, 221) = ( 254 x 221 ) / 56134

= 254 / 221

= 254

Step2:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 254, 221, 680, 655 is 1
