Given numbers are 861, 171, 939, 154

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

Apply this formula for all numbers.

Step1:

LCM(861, 171) = 49077

GCD(861, 171) = ( 861 x 171 ) / 49077

= 861 / 171

= 861

Step2:

LCM(3, 939) = 939

GCD(3, 939) = ( 3 x 939 ) / 939

= 3 / 939

= 3

Step3:

LCM(3, 154) = 462

GCD(3, 154) = ( 3 x 154 ) / 462

= 3 / 154

= 3

So, Greatest Common Divisor of 861, 171, 939, 154 is 1
