Given numbers are 851, 688, 129, 221

The list of prime factors of all numbers are

Prime factors of 851 are 23 x 37

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 129 are 3 x 43

Prime factors of 221 are 13 x 17

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

Given numbers are 851, 688, 129, 221

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

Apply this formula for all numbers.

Step1:

LCM(851, 688) = 585488

GCD(851, 688) = ( 851 x 688 ) / 585488

= 851 / 688

= 851

Step2:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 851, 688, 129, 221 is 1
