Given numbers are 861, 239, 124

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

Apply this formula for all numbers.

Step1:

LCM(861, 239) = 205779

GCD(861, 239) = ( 861 x 239 ) / 205779

= 861 / 239

= 861

Step2:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 861, 239, 124 is 1
