Given numbers are 663, 650, 568, 691

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

Apply this formula for all numbers.

Step1:

LCM(663, 650) = 33150

GCD(663, 650) = ( 663 x 650 ) / 33150

= 663 / 650

= 663

Step2:

LCM(13, 568) = 7384

GCD(13, 568) = ( 13 x 568 ) / 7384

= 13 / 568

= 13

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 663, 650, 568, 691 is 1
