Given numbers are 656, 905, 984, 243

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

Apply this formula for all numbers.

Step1:

LCM(656, 905) = 593680

GCD(656, 905) = ( 656 x 905 ) / 593680

= 656 / 905

= 656

Step2:

LCM(1, 984) = 984

GCD(1, 984) = ( 1 x 984 ) / 984

= 1 / 984

= 1

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 656, 905, 984, 243 is 1
