Given numbers are 759, 805, 389, 639

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

Apply this formula for all numbers.

Step1:

LCM(759, 805) = 26565

GCD(759, 805) = ( 759 x 805 ) / 26565

= 759 / 805

= 759

Step2:

LCM(23, 389) = 8947

GCD(23, 389) = ( 23 x 389 ) / 8947

= 23 / 389

= 23

Step3:

LCM(1, 639) = 639

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

= 1 / 639

= 1

So, Greatest Common Divisor of 759, 805, 389, 639 is 1
