Given numbers are 276, 128, 285, 861

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

Apply this formula for all numbers.

Step1:

LCM(276, 128) = 8832

GCD(276, 128) = ( 276 x 128 ) / 8832

= 276 / 128

= 276

Step2:

LCM(4, 285) = 1140

GCD(4, 285) = ( 4 x 285 ) / 1140

= 4 / 285

= 4

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 276, 128, 285, 861 is 1
