Given numbers are 351, 770, 841, 221

The list of prime factors of all numbers are

Prime factors of 351 are 3 x 3 x 3 x 13

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

Prime factors of 841 are 29 x 29

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 351, 770, 841, 221

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

Apply this formula for all numbers.

Step1:

LCM(351, 770) = 270270

GCD(351, 770) = ( 351 x 770 ) / 270270

= 351 / 770

= 351

Step2:

LCM(1, 841) = 841

GCD(1, 841) = ( 1 x 841 ) / 841

= 1 / 841

= 1

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 351, 770, 841, 221 is 1
