Given numbers are 455, 249, 645, 883

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

Apply this formula for all numbers.

Step1:

LCM(455, 249) = 113295

GCD(455, 249) = ( 455 x 249 ) / 113295

= 455 / 249

= 455

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 883) = 883

GCD(1, 883) = ( 1 x 883 ) / 883

= 1 / 883

= 1

So, Greatest Common Divisor of 455, 249, 645, 883 is 1
