Given numbers are 384, 790, 86, 638

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

Apply this formula for all numbers.

Step1:

LCM(384, 790) = 151680

GCD(384, 790) = ( 384 x 790 ) / 151680

= 384 / 790

= 384

Step2:

LCM(2, 86) = 86

GCD(2, 86) = ( 2 x 86 ) / 86

= 2 / 86

= 2

Step3:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

So, Greatest Common Divisor of 384, 790, 86, 638 is 2
