Given numbers are 691, 329, 815, 916

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

Apply this formula for all numbers.

Step1:

LCM(691, 329) = 227339

GCD(691, 329) = ( 691 x 329 ) / 227339

= 691 / 329

= 691

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

Step3:

LCM(1, 916) = 916

GCD(1, 916) = ( 1 x 916 ) / 916

= 1 / 916

= 1

So, Greatest Common Divisor of 691, 329, 815, 916 is 1
