Given numbers are 693, 686, 344, 409

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

Apply this formula for all numbers.

Step1:

LCM(693, 686) = 67914

GCD(693, 686) = ( 693 x 686 ) / 67914

= 693 / 686

= 693

Step2:

LCM(7, 344) = 2408

GCD(7, 344) = ( 7 x 344 ) / 2408

= 7 / 344

= 7

Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 693, 686, 344, 409 is 1
