The list of prime factors of all numbers are

Prime factors of 818 are 2 x 409

Prime factors of 639 are 3 x 3 x 71

Prime factors of 574 are 2 x 7 x 41

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 818, 639, 574, 480

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

Apply this formula for all numbers.

Step1:

LCM(818, 639) = 522702

GCD(818, 639) = ( 818 x 639 ) / 522702

= 818 / 639

= 818

Step2:

LCM(1, 574) = 574

GCD(1, 574) = ( 1 x 574 ) / 574

= 1 / 574

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 818, 639, 574, 480 is 1
