Given numbers are 621, 818, 721, 808

The list of prime factors of all numbers are

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

Prime factors of 818 are 2 x 409

Prime factors of 721 are 7 x 103

Prime factors of 808 are 2 x 2 x 2 x 101

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

Given numbers are 621, 818, 721, 808

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

Apply this formula for all numbers.

Step1:

LCM(621, 818) = 507978

GCD(621, 818) = ( 621 x 818 ) / 507978

= 621 / 818

= 621

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

So, Greatest Common Divisor of 621, 818, 721, 808 is 1
