Given numbers are 389, 764, 619, 790

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

Apply this formula for all numbers.

Step1:

LCM(389, 764) = 297196

GCD(389, 764) = ( 389 x 764 ) / 297196

= 389 / 764

= 389

Step2:

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

= 1 / 619

= 1

Step3:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

So, Greatest Common Divisor of 389, 764, 619, 790 is 1
