Given numbers are 329, 961, 689, 805

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

Apply this formula for all numbers.

Step1:

LCM(329, 961) = 316169

GCD(329, 961) = ( 329 x 961 ) / 316169

= 329 / 961

= 329

Step2:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

Step3:

LCM(1, 805) = 805

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

= 1 / 805

= 1

So, Greatest Common Divisor of 329, 961, 689, 805 is 1
