Given numbers are 628, 561, 286, 485

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

Apply this formula for all numbers.

Step1:

LCM(628, 561) = 352308

GCD(628, 561) = ( 628 x 561 ) / 352308

= 628 / 561

= 628

Step2:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

Step3:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 628, 561, 286, 485 is 1
