Given numbers are 765, 102, 891, 787

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

Apply this formula for all numbers.

Step1:

LCM(765, 102) = 1530

GCD(765, 102) = ( 765 x 102 ) / 1530

= 765 / 102

= 765

Step2:

LCM(51, 891) = 15147

GCD(51, 891) = ( 51 x 891 ) / 15147

= 51 / 891

= 51

Step3:

LCM(3, 787) = 2361

GCD(3, 787) = ( 3 x 787 ) / 2361

= 3 / 787

= 3

So, Greatest Common Divisor of 765, 102, 891, 787 is 1
