Given numbers are 867, 643, 447, 555

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

Apply this formula for all numbers.

Step1:

LCM(867, 643) = 557481

GCD(867, 643) = ( 867 x 643 ) / 557481

= 867 / 643

= 867

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

So, Greatest Common Divisor of 867, 643, 447, 555 is 1
