Given numbers are 621, 153, 794, 422

The list of prime factors of all numbers are

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

Prime factors of 153 are 3 x 3 x 17

Prime factors of 794 are 2 x 397

Prime factors of 422 are 2 x 211

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

Given numbers are 621, 153, 794, 422

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

Apply this formula for all numbers.

Step1:

LCM(621, 153) = 10557

GCD(621, 153) = ( 621 x 153 ) / 10557

= 621 / 153

= 621

Step2:

LCM(9, 794) = 7146

GCD(9, 794) = ( 9 x 794 ) / 7146

= 9 / 794

= 9

Step3:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

So, Greatest Common Divisor of 621, 153, 794, 422 is 1
