Given numbers are 861, 287, 470, 713

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

Apply this formula for all numbers.

Step1:

LCM(861, 287) = 861

GCD(861, 287) = ( 861 x 287 ) / 861

= 861 / 287

= 861

Step2:

LCM(287, 470) = 134890

GCD(287, 470) = ( 287 x 470 ) / 134890

= 287 / 470

= 287

Step3:

LCM(1, 713) = 713

GCD(1, 713) = ( 1 x 713 ) / 713

= 1 / 713

= 1

So, Greatest Common Divisor of 861, 287, 470, 713 is 1
