The list of prime factors of all numbers are

Prime factors of 772 are 2 x 2 x 193

Prime factors of 406 are 2 x 7 x 29

Prime factors of 221 are 13 x 17

Prime factors of 371 are 7 x 53

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

Given numbers are 772, 406, 221, 371

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

Apply this formula for all numbers.

Step1:

LCM(772, 406) = 156716

GCD(772, 406) = ( 772 x 406 ) / 156716

= 772 / 406

= 772

Step2:

LCM(2, 221) = 442

GCD(2, 221) = ( 2 x 221 ) / 442

= 2 / 221

= 2

Step3:

LCM(1, 371) = 371

GCD(1, 371) = ( 1 x 371 ) / 371

= 1 / 371

= 1

So, Greatest Common Divisor of 772, 406, 221, 371 is 1
