Given numbers are 628, 187, 655, 868

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

Apply this formula for all numbers.

Step1:

LCM(628, 187) = 117436

GCD(628, 187) = ( 628 x 187 ) / 117436

= 628 / 187

= 628

Step2:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

Step3:

LCM(1, 868) = 868

GCD(1, 868) = ( 1 x 868 ) / 868

= 1 / 868

= 1

So, Greatest Common Divisor of 628, 187, 655, 868 is 1
