Given numbers are 393, 358, 814, 639

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

Apply this formula for all numbers.

Step1:

LCM(393, 358) = 140694

GCD(393, 358) = ( 393 x 358 ) / 140694

= 393 / 358

= 393

Step2:

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

= 1 / 814

= 1

Step3:

LCM(1, 639) = 639

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

= 1 / 639

= 1

So, Greatest Common Divisor of 393, 358, 814, 639 is 1
