Given numbers are 765, 837, 398, 139

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

Apply this formula for all numbers.

Step1:

LCM(765, 837) = 71145

GCD(765, 837) = ( 765 x 837 ) / 71145

= 765 / 837

= 765

Step2:

LCM(9, 398) = 3582

GCD(9, 398) = ( 9 x 398 ) / 3582

= 9 / 398

= 9

Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

So, Greatest Common Divisor of 765, 837, 398, 139 is 1
