Given numbers are 861, 130, 177

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

Apply this formula for all numbers.

Step1:

LCM(861, 130) = 111930

GCD(861, 130) = ( 861 x 130 ) / 111930

= 861 / 130

= 861

Step2:

LCM(1, 177) = 177

GCD(1, 177) = ( 1 x 177 ) / 177

= 1 / 177

= 1

So, Greatest Common Divisor of 861, 130, 177 is 1
