Given numbers are 861, 986, 54

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

Apply this formula for all numbers.

Step1:

LCM(861, 986) = 848946

GCD(861, 986) = ( 861 x 986 ) / 848946

= 861 / 986

= 861

Step2:

LCM(1, 54) = 54

GCD(1, 54) = ( 1 x 54 ) / 54

= 1 / 54

= 1

So, Greatest Common Divisor of 861, 986, 54 is 1
