Given numbers are 209, 988, 427, 683

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

Apply this formula for all numbers.

Step1:

LCM(209, 988) = 10868

GCD(209, 988) = ( 209 x 988 ) / 10868

= 209 / 988

= 209

Step2:

LCM(19, 427) = 8113

GCD(19, 427) = ( 19 x 427 ) / 8113

= 19 / 427

= 19

Step3:

LCM(1, 683) = 683

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

= 1 / 683

= 1

So, Greatest Common Divisor of 209, 988, 427, 683 is 1
