Given numbers are 789, 823, 409, 865

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

Apply this formula for all numbers.

Step1:

LCM(789, 823) = 649347

GCD(789, 823) = ( 789 x 823 ) / 649347

= 789 / 823

= 789

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 789, 823, 409, 865 is 1
