Given numbers are 530, 854, 668, 215

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 854 are 2 x 7 x 61

Prime factors of 668 are 2 x 2 x 167

Prime factors of 215 are 5 x 43

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

Given numbers are 530, 854, 668, 215

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

Apply this formula for all numbers.

Step1:

LCM(530, 854) = 226310

GCD(530, 854) = ( 530 x 854 ) / 226310

= 530 / 854

= 530

Step2:

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

= 2 / 668

= 2

Step3:

LCM(2, 215) = 430

GCD(2, 215) = ( 2 x 215 ) / 430

= 2 / 215

= 2

So, Greatest Common Divisor of 530, 854, 668, 215 is 1
