Given numbers are 611, 771, 861

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

Apply this formula for all numbers.

Step1:

LCM(611, 771) = 471081

GCD(611, 771) = ( 611 x 771 ) / 471081

= 611 / 771

= 611

Step2:

LCM(1, 861) = 861

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

= 1 / 861

= 1

So, Greatest Common Divisor of 611, 771, 861 is 1
