Given numbers are 864, 123, 392, 281

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

Apply this formula for all numbers.

Step1:

LCM(864, 123) = 35424

GCD(864, 123) = ( 864 x 123 ) / 35424

= 864 / 123

= 864

Step2:

LCM(3, 392) = 1176

GCD(3, 392) = ( 3 x 392 ) / 1176

= 3 / 392

= 3

Step3:

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

= 1 / 281

= 1

So, Greatest Common Divisor of 864, 123, 392, 281 is 1
