Given numbers are 627, 163, 285, 646

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

Apply this formula for all numbers.

Step1:

LCM(627, 163) = 102201

GCD(627, 163) = ( 627 x 163 ) / 102201

= 627 / 163

= 627

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 627, 163, 285, 646 is 1
