Given numbers are 861, 618, 866, 897

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

Apply this formula for all numbers.

Step1:

LCM(861, 618) = 177366

GCD(861, 618) = ( 861 x 618 ) / 177366

= 861 / 618

= 861

Step2:

LCM(3, 866) = 2598

GCD(3, 866) = ( 3 x 866 ) / 2598

= 3 / 866

= 3

Step3:

LCM(1, 897) = 897

GCD(1, 897) = ( 1 x 897 ) / 897

= 1 / 897

= 1

So, Greatest Common Divisor of 861, 618, 866, 897 is 1
