Given numbers are 659, 685, 389, 612

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

Apply this formula for all numbers.

Step1:

LCM(659, 685) = 451415

GCD(659, 685) = ( 659 x 685 ) / 451415

= 659 / 685

= 659

Step2:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

Step3:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

So, Greatest Common Divisor of 659, 685, 389, 612 is 1
