Given numbers are 691, 905, 805, 410

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

Apply this formula for all numbers.

Step1:

LCM(691, 905) = 625355

GCD(691, 905) = ( 691 x 905 ) / 625355

= 691 / 905

= 691

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

Step3:

LCM(1, 410) = 410

GCD(1, 410) = ( 1 x 410 ) / 410

= 1 / 410

= 1

So, Greatest Common Divisor of 691, 905, 805, 410 is 1
