Given numbers are 656, 197, 819, 849

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

Apply this formula for all numbers.

Step1:

LCM(656, 197) = 129232

GCD(656, 197) = ( 656 x 197 ) / 129232

= 656 / 197

= 656

Step2:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

Step3:

LCM(1, 849) = 849

GCD(1, 849) = ( 1 x 849 ) / 849

= 1 / 849

= 1

So, Greatest Common Divisor of 656, 197, 819, 849 is 1
