Given numbers are 621, 580, 396, 564

The list of prime factors of all numbers are

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

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

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 564 are 2 x 2 x 3 x 47

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

Given numbers are 621, 580, 396, 564

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

Apply this formula for all numbers.

Step1:

LCM(621, 580) = 360180

GCD(621, 580) = ( 621 x 580 ) / 360180

= 621 / 580

= 621

Step2:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

Step3:

LCM(1, 564) = 564

GCD(1, 564) = ( 1 x 564 ) / 564

= 1 / 564

= 1

So, Greatest Common Divisor of 621, 580, 396, 564 is 1
