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

Apply this formula for all numbers.

Step1:

LCM(409, 697) = 285073

GCD(409, 697) = ( 409 x 697 ) / 285073

= 409 / 697

= 409

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 409, 697, 620 is 1
