Given numbers are 161, 621, 351, 371

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 621 are 3 x 3 x 3 x 23

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

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 161, 621, 351, 371

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

Apply this formula for all numbers.

Step1:

LCM(161, 621) = 4347

GCD(161, 621) = ( 161 x 621 ) / 4347

= 161 / 621

= 161

Step2:

LCM(23, 351) = 8073

GCD(23, 351) = ( 23 x 351 ) / 8073

= 23 / 351

= 23

Step3:

LCM(1, 371) = 371

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

= 1 / 371

= 1

So, Greatest Common Divisor of 161, 621, 351, 371 is 1
