Given numbers are 891, 351, 585, 305

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

Apply this formula for all numbers.

Step1:

LCM(891, 351) = 11583

GCD(891, 351) = ( 891 x 351 ) / 11583

= 891 / 351

= 891

Step2:

LCM(27, 585) = 1755

GCD(27, 585) = ( 27 x 585 ) / 1755

= 27 / 585

= 27

Step3:

LCM(9, 305) = 2745

GCD(9, 305) = ( 9 x 305 ) / 2745

= 9 / 305

= 9

So, Greatest Common Divisor of 891, 351, 585, 305 is 1
