Given numbers are 388, 686, 398, 533

The list of prime factors of all numbers are

Prime factors of 388 are 2 x 2 x 97

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

Prime factors of 398 are 2 x 199

Prime factors of 533 are 13 x 41

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

Given numbers are 388, 686, 398, 533

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

Apply this formula for all numbers.

Step1:

LCM(388, 686) = 133084

GCD(388, 686) = ( 388 x 686 ) / 133084

= 388 / 686

= 388

Step2:

LCM(2, 398) = 398

GCD(2, 398) = ( 2 x 398 ) / 398

= 2 / 398

= 2

Step3:

LCM(2, 533) = 1066

GCD(2, 533) = ( 2 x 533 ) / 1066

= 2 / 533

= 2

So, Greatest Common Divisor of 388, 686, 398, 533 is 1
