Given numbers are 638, 479, 390, 794

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

Apply this formula for all numbers.

Step1:

LCM(638, 479) = 305602

GCD(638, 479) = ( 638 x 479 ) / 305602

= 638 / 479

= 638

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 794) = 794

GCD(1, 794) = ( 1 x 794 ) / 794

= 1 / 794

= 1

So, Greatest Common Divisor of 638, 479, 390, 794 is 1
