Given numbers are 217, 558, 386, 634

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 386 are 2 x 193

Prime factors of 634 are 2 x 317

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

Given numbers are 217, 558, 386, 634

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

Apply this formula for all numbers.

Step1:

LCM(217, 558) = 3906

GCD(217, 558) = ( 217 x 558 ) / 3906

= 217 / 558

= 217

Step2:

LCM(31, 386) = 11966

GCD(31, 386) = ( 31 x 386 ) / 11966

= 31 / 386

= 31

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 217, 558, 386, 634 is 1
