Given numbers are 345, 580, 920, 621

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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 345, 580, 920, 621

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

Apply this formula for all numbers.

Step1:

LCM(345, 580) = 40020

GCD(345, 580) = ( 345 x 580 ) / 40020

= 345 / 580

= 345

Step2:

LCM(5, 920) = 920

GCD(5, 920) = ( 5 x 920 ) / 920

= 5 / 920

= 5

Step3:

LCM(5, 621) = 3105

GCD(5, 621) = ( 5 x 621 ) / 3105

= 5 / 621

= 5

So, Greatest Common Divisor of 345, 580, 920, 621 is 1
