Given numbers are 809, 777, 181, 861

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

Apply this formula for all numbers.

Step1:

LCM(809, 777) = 628593

GCD(809, 777) = ( 809 x 777 ) / 628593

= 809 / 777

= 809

Step2:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 809, 777, 181, 861 is 1
