Given numbers are 618, 897, 861, 858

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

Apply this formula for all numbers.

Step1:

LCM(618, 897) = 184782

GCD(618, 897) = ( 618 x 897 ) / 184782

= 618 / 897

= 618

Step2:

LCM(3, 861) = 861

GCD(3, 861) = ( 3 x 861 ) / 861

= 3 / 861

= 3

Step3:

LCM(3, 858) = 858

GCD(3, 858) = ( 3 x 858 ) / 858

= 3 / 858

= 3

So, Greatest Common Divisor of 618, 897, 861, 858 is 3
