Given numbers are 787, 770, 189, 856

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

Apply this formula for all numbers.

Step1:

LCM(787, 770) = 605990

GCD(787, 770) = ( 787 x 770 ) / 605990

= 787 / 770

= 787

Step2:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

Step3:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

So, Greatest Common Divisor of 787, 770, 189, 856 is 1
