Given numbers are 693, 979, 721, 205

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

Apply this formula for all numbers.

Step1:

LCM(693, 979) = 61677

GCD(693, 979) = ( 693 x 979 ) / 61677

= 693 / 979

= 693

Step2:

LCM(11, 721) = 7931

GCD(11, 721) = ( 11 x 721 ) / 7931

= 11 / 721

= 11

Step3:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

So, Greatest Common Divisor of 693, 979, 721, 205 is 1
