Given numbers are 530, 108, 818, 821

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

Prime factors of 818 are 2 x 409

Prime factors of 821 are 821

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

Given numbers are 530, 108, 818, 821

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

Apply this formula for all numbers.

Step1:

LCM(530, 108) = 28620

GCD(530, 108) = ( 530 x 108 ) / 28620

= 530 / 108

= 530

Step2:

LCM(2, 818) = 818

GCD(2, 818) = ( 2 x 818 ) / 818

= 2 / 818

= 2

Step3:

LCM(2, 821) = 1642

GCD(2, 821) = ( 2 x 821 ) / 1642

= 2 / 821

= 2

So, Greatest Common Divisor of 530, 108, 818, 821 is 1
