Given numbers are 301, 287, 770, 221

The list of prime factors of all numbers are

Prime factors of 301 are 7 x 43

Prime factors of 287 are 7 x 41

Prime factors of 770 are 2 x 5 x 7 x 11

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 301, 287, 770, 221

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

Apply this formula for all numbers.

Step1:

LCM(301, 287) = 12341

GCD(301, 287) = ( 301 x 287 ) / 12341

= 301 / 287

= 301

Step2:

LCM(7, 770) = 770

GCD(7, 770) = ( 7 x 770 ) / 770

= 7 / 770

= 7

Step3:

LCM(7, 221) = 1547

GCD(7, 221) = ( 7 x 221 ) / 1547

= 7 / 221

= 7

So, Greatest Common Divisor of 301, 287, 770, 221 is 1
