Given numbers are 664, 819, 255, 830

The list of prime factors of all numbers are

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 255 are 3 x 5 x 17

Prime factors of 830 are 2 x 5 x 83

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

Given numbers are 664, 819, 255, 830

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

Apply this formula for all numbers.

Step1:

LCM(664, 819) = 543816

GCD(664, 819) = ( 664 x 819 ) / 543816

= 664 / 819

= 664

Step2:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 664, 819, 255, 830 is 1
