Given numbers are 690, 311, 809, 683

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

Apply this formula for all numbers.

Step1:

LCM(690, 311) = 214590

GCD(690, 311) = ( 690 x 311 ) / 214590

= 690 / 311

= 690

Step2:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

Step3:

LCM(1, 683) = 683

GCD(1, 683) = ( 1 x 683 ) / 683

= 1 / 683

= 1

So, Greatest Common Divisor of 690, 311, 809, 683 is 1
