Given numbers are 973, 728, 439, 309

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

Apply this formula for all numbers.

Step1:

LCM(973, 728) = 101192

GCD(973, 728) = ( 973 x 728 ) / 101192

= 973 / 728

= 973

Step2:

LCM(7, 439) = 3073

GCD(7, 439) = ( 7 x 439 ) / 3073

= 7 / 439

= 7

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 973, 728, 439, 309 is 1
