Given numbers are 515, 191, 220, 866

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 191 are 191

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 866 are 2 x 433

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

Given numbers are 515, 191, 220, 866

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

Apply this formula for all numbers.

Step1:

LCM(515, 191) = 98365

GCD(515, 191) = ( 515 x 191 ) / 98365

= 515 / 191

= 515

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 866) = 866

GCD(1, 866) = ( 1 x 866 ) / 866

= 1 / 866

= 1

So, Greatest Common Divisor of 515, 191, 220, 866 is 1
