Given numbers are 861, 854, 973, 256

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

Apply this formula for all numbers.

Step1:

LCM(861, 854) = 105042

GCD(861, 854) = ( 861 x 854 ) / 105042

= 861 / 854

= 861

Step2:

LCM(7, 973) = 973

GCD(7, 973) = ( 7 x 973 ) / 973

= 7 / 973

= 7

Step3:

LCM(7, 256) = 1792

GCD(7, 256) = ( 7 x 256 ) / 1792

= 7 / 256

= 7

So, Greatest Common Divisor of 861, 854, 973, 256 is 1
