Given numbers are 206, 388, 656, 697

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

Apply this formula for all numbers.

Step1:

LCM(206, 388) = 39964

GCD(206, 388) = ( 206 x 388 ) / 39964

= 206 / 388

= 206

Step2:

LCM(2, 656) = 656

GCD(2, 656) = ( 2 x 656 ) / 656

= 2 / 656

= 2

Step3:

LCM(2, 697) = 1394

GCD(2, 697) = ( 2 x 697 ) / 1394

= 2 / 697

= 2

So, Greatest Common Divisor of 206, 388, 656, 697 is 1
