Given numbers are 645, 873, 264, 449

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

Apply this formula for all numbers.

Step1:

LCM(645, 873) = 187695

GCD(645, 873) = ( 645 x 873 ) / 187695

= 645 / 873

= 645

Step2:

LCM(3, 264) = 264

GCD(3, 264) = ( 3 x 264 ) / 264

= 3 / 264

= 3

Step3:

LCM(3, 449) = 1347

GCD(3, 449) = ( 3 x 449 ) / 1347

= 3 / 449

= 3

So, Greatest Common Divisor of 645, 873, 264, 449 is 1
