Given numbers are 218, 582, 420, 865

The list of prime factors of all numbers are

Prime factors of 218 are 2 x 109

Prime factors of 582 are 2 x 3 x 97

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 865 are 5 x 173

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

Given numbers are 218, 582, 420, 865

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

Apply this formula for all numbers.

Step1:

LCM(218, 582) = 63438

GCD(218, 582) = ( 218 x 582 ) / 63438

= 218 / 582

= 218

Step2:

LCM(2, 420) = 420

GCD(2, 420) = ( 2 x 420 ) / 420

= 2 / 420

= 2

Step3:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

So, Greatest Common Divisor of 218, 582, 420, 865 is 1
