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

Apply this formula for all numbers.

Step1:

LCM(678, 698) = 236622

GCD(678, 698) = ( 678 x 698 ) / 236622

= 678 / 698

= 678

Step2:

LCM(2, 397) = 794

GCD(2, 397) = ( 2 x 397 ) / 794

= 2 / 397

= 2

So, Greatest Common Divisor of 678, 698, 397 is 1
