Given numbers are 645, 267, 206, 629

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

Apply this formula for all numbers.

Step1:

LCM(645, 267) = 57405

GCD(645, 267) = ( 645 x 267 ) / 57405

= 645 / 267

= 645

Step2:

LCM(3, 206) = 618

GCD(3, 206) = ( 3 x 206 ) / 618

= 3 / 206

= 3

Step3:

LCM(1, 629) = 629

GCD(1, 629) = ( 1 x 629 ) / 629

= 1 / 629

= 1

So, Greatest Common Divisor of 645, 267, 206, 629 is 1
