Given numbers are 647, 284, 883, 905

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

Apply this formula for all numbers.

Step1:

LCM(647, 284) = 183748

GCD(647, 284) = ( 647 x 284 ) / 183748

= 647 / 284

= 647

Step2:

LCM(1, 883) = 883

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

= 1 / 883

= 1

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 647, 284, 883, 905 is 1
