Given numbers are 340, 235, 781, 621

The list of prime factors of all numbers are

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 235 are 5 x 47

Prime factors of 781 are 11 x 71

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

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

Given numbers are 340, 235, 781, 621

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

Apply this formula for all numbers.

Step1:

LCM(340, 235) = 15980

GCD(340, 235) = ( 340 x 235 ) / 15980

= 340 / 235

= 340

Step2:

LCM(5, 781) = 3905

GCD(5, 781) = ( 5 x 781 ) / 3905

= 5 / 781

= 5

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 340, 235, 781, 621 is 1
