Given numbers are 891, 243, 985, 321

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

Apply this formula for all numbers.

Step1:

LCM(891, 243) = 2673

GCD(891, 243) = ( 891 x 243 ) / 2673

= 891 / 243

= 891

Step2:

LCM(81, 985) = 79785

GCD(81, 985) = ( 81 x 985 ) / 79785

= 81 / 985

= 81

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 891, 243, 985, 321 is 1
