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

Apply this formula for all numbers.

Step1:

LCM(399, 523) = 208677

GCD(399, 523) = ( 399 x 523 ) / 208677

= 399 / 523

= 399

Step2:

LCM(1, 39) = 39

GCD(1, 39) = ( 1 x 39 ) / 39

= 1 / 39

= 1

So, Greatest Common Divisor of 399, 523, 39 is 1
