Given numbers are 393, 641, 972, 339

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

Apply this formula for all numbers.

Step1:

LCM(393, 641) = 251913

GCD(393, 641) = ( 393 x 641 ) / 251913

= 393 / 641

= 393

Step2:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

Step3:

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

= 1 / 339

= 1

So, Greatest Common Divisor of 393, 641, 972, 339 is 1
