Given numbers are 663, 845, 397, 673

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

Apply this formula for all numbers.

Step1:

LCM(663, 845) = 43095

GCD(663, 845) = ( 663 x 845 ) / 43095

= 663 / 845

= 663

Step2:

LCM(13, 397) = 5161

GCD(13, 397) = ( 13 x 397 ) / 5161

= 13 / 397

= 13

Step3:

LCM(1, 673) = 673

GCD(1, 673) = ( 1 x 673 ) / 673

= 1 / 673

= 1

So, Greatest Common Divisor of 663, 845, 397, 673 is 1
