Given numbers are 530, 391, 686, 828

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 391 are 17 x 23

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 530, 391, 686, 828

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

Apply this formula for all numbers.

Step1:

LCM(530, 391) = 207230

GCD(530, 391) = ( 530 x 391 ) / 207230

= 530 / 391

= 530

Step2:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 530, 391, 686, 828 is 1
