The list of prime factors of all numbers are

Prime factors of 967 are 967

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

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 967, 621, 140, 420

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

Apply this formula for all numbers.

Step1:

LCM(967, 621) = 600507

GCD(967, 621) = ( 967 x 621 ) / 600507

= 967 / 621

= 967

Step2:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 967, 621, 140, 420 is 1
