Given numbers are 319, 561, 331, 209

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

Apply this formula for all numbers.

Step1:

LCM(319, 561) = 16269

GCD(319, 561) = ( 319 x 561 ) / 16269

= 319 / 561

= 319

Step2:

LCM(11, 331) = 3641

GCD(11, 331) = ( 11 x 331 ) / 3641

= 11 / 331

= 11

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 319, 561, 331, 209 is 1
