Given numbers are 205, 656, 355, 797

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

Apply this formula for all numbers.

Step1:

LCM(205, 656) = 3280

GCD(205, 656) = ( 205 x 656 ) / 3280

= 205 / 656

= 205

Step2:

LCM(41, 355) = 14555

GCD(41, 355) = ( 41 x 355 ) / 14555

= 41 / 355

= 41

Step3:

LCM(1, 797) = 797

GCD(1, 797) = ( 1 x 797 ) / 797

= 1 / 797

= 1

So, Greatest Common Divisor of 205, 656, 355, 797 is 1
