Given numbers are 579, 820, 738, 621

The list of prime factors of all numbers are

Prime factors of 579 are 3 x 193

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 738 are 2 x 3 x 3 x 41

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 579, 820, 738, 621

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

Apply this formula for all numbers.

Step1:

LCM(579, 820) = 474780

GCD(579, 820) = ( 579 x 820 ) / 474780

= 579 / 820

= 579

Step2:

LCM(1, 738) = 738

GCD(1, 738) = ( 1 x 738 ) / 738

= 1 / 738

= 1

Step3:

LCM(1, 621) = 621

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

= 1 / 621

= 1

So, Greatest Common Divisor of 579, 820, 738, 621 is 1
