Given numbers are 318, 861, 283, 721

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

Apply this formula for all numbers.

Step1:

LCM(318, 861) = 91266

GCD(318, 861) = ( 318 x 861 ) / 91266

= 318 / 861

= 318

Step2:

LCM(3, 283) = 849

GCD(3, 283) = ( 3 x 283 ) / 849

= 3 / 283

= 3

Step3:

LCM(1, 721) = 721

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

= 1 / 721

= 1

So, Greatest Common Divisor of 318, 861, 283, 721 is 1
