The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 219 are 3 x 73

Prime factors of 218 are 2 x 109

Prime factors of 721 are 7 x 103

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

Given numbers are 285, 219, 218, 721

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

Apply this formula for all numbers.

Step1:

LCM(285, 219) = 20805

GCD(285, 219) = ( 285 x 219 ) / 20805

= 285 / 219

= 285

Step2:

LCM(3, 218) = 654

GCD(3, 218) = ( 3 x 218 ) / 654

= 3 / 218

= 3

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 285, 219, 218, 721 is 1
