Given numbers are 188, 717, 415, 621

The list of prime factors of all numbers are

Prime factors of 188 are 2 x 2 x 47

Prime factors of 717 are 3 x 239

Prime factors of 415 are 5 x 83

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 188, 717, 415, 621

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

Apply this formula for all numbers.

Step1:

LCM(188, 717) = 134796

GCD(188, 717) = ( 188 x 717 ) / 134796

= 188 / 717

= 188

Step2:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

Step3:

LCM(1, 621) = 621

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

= 1 / 621

= 1

So, Greatest Common Divisor of 188, 717, 415, 621 is 1
