Given numbers are 691, 566, 353, 891

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

Apply this formula for all numbers.

Step1:

LCM(691, 566) = 391106

GCD(691, 566) = ( 691 x 566 ) / 391106

= 691 / 566

= 691

Step2:

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

= 1 / 353

= 1

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 691, 566, 353, 891 is 1
