Given numbers are 309, 409, 639, 583

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

Apply this formula for all numbers.

Step1:

LCM(309, 409) = 126381

GCD(309, 409) = ( 309 x 409 ) / 126381

= 309 / 409

= 309

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 583) = 583

GCD(1, 583) = ( 1 x 583 ) / 583

= 1 / 583

= 1

So, Greatest Common Divisor of 309, 409, 639, 583 is 1
